i'm going to wait for the scanner from Matterform. http://www.matterform.net/ Looks very promising at half the price.
i have the DLink DIR-655 and it can do this. i have my local wireless and a "guest" wireless and neither can see each other. i also have QOS on the guest line to throttle down the speeds. guests (and neighbours) can use it, but it's not going to be a great "long-term" solution.
Evan did an exceptional job of "shedding the digital identity". He manipulated IP addresses (via TOR and RDP) and travelled via untrackable gift cards, etc. He was only caught (on the last day) by getting suckered in to a "bonus game" offered by wired (to attend a book reading). obviously, a stake out there would result in a hit. A very interesting read.
setting static IP has been broken in ubuntu for a couple of releases now, i don't see why nobody has fixed it yet. each time, i end up installing wicd to manage my network connections http://wicd.sourceforge.net/
I know, don't feed the troll. however, it should be noted that 7 is really quite good. i've been a windows user, a mac user and i have tried every flavour of linux for 10 years and i stand by my opinion that Win7 is an excellent OS. Each has their strengths (and i have each installed on various machines for various jobs), but everyone shouldn't be assaulting every MS news item just because it's MS.
I recently just dumped my linux server from my house. not from lack of love, but from lack of space. i replaced it with the DNS-323 from Linksys. it's a NAS box (2 drives) that is easily hacked to run linux. the tiny box now serves as my web server, ftp server, upnp video/music server, torrents, the whole enchilada. all in a box the size of 2 hard drives. i have the whole thing tucked in a back cupboard. much easier and quieter than a full system.
