With respect to the use of FreeNX, part of my Utopian setup is a
CentOS server running a paravirtualized, Edubuntu-themed desktop, a
paravirtualized Debian Desktop providing DRBL services, and a
paravirtualized LDAP/NFS/SAMBA/PDC server. Both the CentOS server and
the Ubuntu Desktop accept connections via FreeNX. The compression
algorithm is outstanding, and the packages are maintained in
A client, be it a PXE booting netbook, a USB booting netbook, or any
computer running a nxclient, connects, compresses, authenticates,
loads a profile, and gets going. Here's the thing - the client can be
in your LAN, it can at the students' home, it can be one of our
transitional homeless in Hawaii using a netbook through free public
wifi, from the hospital if your kid is sick, on vacation if you are
traveling, etc., etc., etc. The magical gigabit connection we are
used to seeking is automagically compressed into the freenx connection
wherever you choose to make your LAN.
Utopian LAN - all desktop are BIOS locked to pxe/etherboot/gpxe boot.
Boot options, be they from flash, pxe, hard drive, pxe to http, etc -
are controlled by the gpxe boot menu and administered remotely. How
does one achieve, and how will google achieve, the ubiquitous roaming
Desktop via the web - the NX compression integrated into the BIOS or
as part of your pre-configured flash drive. I've been doing it with
my netbooks since last year, and it's scary good.
