We have used meet.jit.si extensively over the last month. It is very usable for small to medium Groups (5-12 persons) if you focus on sharing the content and use the Audio.
The feature set is quite good and it allows high resolution Videostreams to all partecipants right away which zoom doesn't, albeit with Resource issues if everyone in the group broadcasts at the same time.

Cheers

Bill Gates doesn't get it. - Again -

He didn't get it on the Internet in 1995 and doesn't get it for renewables in 2011.

Nuclear power is only cheap if you don't include the waste disposal and the riscmanagement in the price.
If you think otherwise go to Chernobyl or Fukushima and se for yourself.

As for the disposal. No longterm deposit has been errected so far - world wide.

Including these risks onely in the Energy prices would mean to quadrupel the price per kwH.

Not to mention some other problems:
Scarcity of Uranium. Some Experts speak of "Peak Uranium" in analogy to Peak Oil.
Many nuclear byproducts are not only dangerous radioactiv matirials, some are among the most effective poisons known to man.

So please Bill, do some serious research on the subject, before blurting out some lobbiest DUMMTALK.

There is only on way to make the planet happier and better with nuclear power:
Shut it down ASAP.!

Thanks folks.

Going back to sleep now. ;-)

Obviously they have.
It's called Linux!

Hi there,

here is my Setup for a small Company with low budget.
This is work in progress so please be gentle.

Serverbased on http://www.zentyal.org/. Comes with everything preconfigured. Uses ubuntu as OS.
Hardware depends on your budget. I used these services
- Mailserver
- Fileserver (Samba)
- E-Groupware as CMS and Resources/Projektmanagement (ZARAFA is the new default Groupware, but i haven't tried it yet)
- LDAP for usermanagement and adresses
- OpenRadius (Optional if you want authentification) - Disabled as we don't use wireless.

Website Outsourced to hoster. This ist simply too complex to handle ourselves.

Clientsside:

Used Laptops (IBM T42 or T60) for around 200-300€ each.
Software:
- Win XP preinstalled. Ubuntu might be an alternative.
- OOO for normal work.
- Firefox/Thunderbird for Mail/Web using LDAP for Contacts
- File-syncing with Toucan
- E-groupware on the server for Calendar/Mail/Ressourceplaning

For the Clients using cheap used laptops means, you can buy newer ones every year. Broken ones are just replaced.

I use Funambol to Sync mobile phones Contacts with the LDAP server. IMAP for Mail. If you want Push services you can look into Z-Push, wich is part of ZAFARA.

I just started, so some parts are still under testing.

Hope this gives you some Ideas.

Have a look at GMX. they are one of the biggest E-mail providers in Europe, (mostly Germany and Austria)
http://www.gmx.de/
As far as i know, they have a 100% non MS Solution.
Mostly Linux clusters.
They seem to scale pretty well.

Hope this helps.

Greetings
