Debian installed in Flash instead of uSD

awesome!
could you please put it into the wiki, debian page?
one thing for apt-get:
- you may install apt-zip -- it creates a script that downloads the  
packages to update elsewhere
- maybe it would be sensible to use a shared folder of your host as apt  
cache folder

both things together in a nice script would allow you to upgrade your fr  
w/o undue worries about space, since all packages are on your host.
