I thought that the standard is French :-))) (Just teasing you. The standard is really different for every social group.)

Never mind. Does anybody actually really care since we have translate.google.com? I really don't. I will gladly start writing in my mother language too without feeling sorry that so many I-Speak-Only-English people might miss my bright ideas. :-)

And anyway isn't it nice that so many Chinese philosophical writings are to be found on internet in their original language...

Honestly. English speakers - are you afraid that people will abandon English or rather that you will stop understanding the rest of the world or that you will be forced to learn other language to communicate? Either one is not going to happen. Don't worry. Just the communication will become more natural to so many people while keeping the information interchange even more vivid. ;-)

One of the Russian comments points out that the software is in fact French PERICOLOR-1000 translated to Russian.

Same as fining the bus driver for transporting the bad guy who later stole valet and took the bus to get back home. Is driver responsible for whom he transports? Should the driver secure the buss against unauthorized third parties abusing the law?

Should not be the securing of the valet (copyrighted material) be responsibility of the owner?

If firefox has the search randomizer then it might have other extensions?

For example extension that
- keeps different sets of cookies for different URLs based on well-defined URL patterns. (this way the search may use different or none cookies then your Gmail pages or Reader or...)
- uses proxy based on the URL patterns (this way your queries to search pages are routed through different way then your Gmail pages...)

For the starter this should satisfy most common needs for a privacy, right?

The XMLHttpRequest can be pretty fast when optimized for performance. There is plenty of time to request a lock and pull information about all current editors from the server between user clicking on "Edit" and focusing on the edited information and moving hands from the mouse back to keyboard... ;-) Lot of time to warn/notify/forbid the first edit before it really happens.

Other approach is revisions. User might be informed that there is somebody else editing and the user might choose to request the lock/ignore warning. If ignored then the latest saved
a) wins - overwrites earliest (but thanks the revisions nothing is permanently lost so all overwritten info can be recovered)
b) the DIFF user interface is brought up and user may try to merge all changes that happened in the meantime into his/her revision before really saving (can be automated - depends on type of data and extent of changes, you can use open source diff tool that is provided as a library to many languages including PHP...)

I will buy an allotment. However steps on my property first will be sued for breaking into my non-existent house and I will demand that the burglar builds the house for me. With proper anti-burglar features like proper doors, cameras, wires, walls, fences, "My Property" signs... :-) Isn't it paradox? How could you break the security in the case that there were no security? Is it possible to break something that does not exist? Can you be ordered to create something that didn't exist before by reasoning that you did break it before?

Sorry, is it just my bad English that forces my Slavic brain no to get the idea?

Sure! I am doing it now! Although I am not as rich as you imply that one must be... I am having good paid job that allows me to work only few hours a day to cover my expenses... And the rest is dedicated... wait... to programming of the project of my choice! Which is Web CMS written in XUL. :-) :-) Simply put. One does not need to be that rich to be able to afford the same comfort as the aforementioned people do! Sure, I don't have 4 Boings and 3 yachts and 7 financial advisers.... but still I get as big satisfaction from my project as they do. As my sister says: How much of a ham can you eat every day? If you are rich (very relative term) you can eat 0.5Kg of ham a day. If you are superrich, can you eat more? No, you cannot. So why to hassle to be superrich?

Run the script on some event that the Google will not emulate.

For example: [Write me] where the link has something like href="javascript:decodeMail();"

(And at best program the web form that will submit it to you on the server side without revealing your address ;-)

Google is just a search engine. They need document management. :-) Correct me if it is not the thing called content management they need?

Import it into some CMS, sort it and make it available through the website secured by the password. We did something like this for http://www.olympus-ims.com/ (but these are public documents) and it really contains thousands of documents (in dozen languages) together with all the document revisions it is over the hundred of thousands of documents. Easy to search, easy to navigate, easy to manage.

Simply: CMS is what you need. Do research.
