Windows XP Multiuser Remote Desktop:
With a couple file renames and a registry change, XP can run three remote desktop sessions (normal desktop plus 2 more).
Combined with the $20-30 terminals that are available from outlets like www.surpluscomputers.com, and the $150-250 LCD screens, you can extend an ordinary PC to multiple users (with very low power and zero noise to boot). 9:55:29 PM

Linksys courts Linux hackers with WRT54G"L"
: The ubiquitous Linksys wifi router is now manufactured with a non-Linux O/S (Vxworks) with half the flash and RAM. The "new" linux version is the unmodified old one, that has been modified
for new features. Some instructions
tell how to route from wireless to wired (though I think the latest WRT's may do that without modification just by using their non-gateway router mode). 10:09:28 PM
Powerline Ethernet Adapters:
Current (Sept 06) situation appears that residential powerline standard is around 14 mbps, but that different vendors extend it up to 200 mbps max. Carrying HD signals at 28 mbps is an important threshold, with conventional digital video of 20 mbps also important. Netgear does well, as does Zyxel.
Both are $100-120 per adaptor. Linksys has older models at 14 mbps only selling for $65 per adaptor or used down to $30. Both Linksys and Zyxel have adaptors for USB at about the same price as Ethernet. 9:59:39 PM
