Thinstation is a thin client linux distro using std. x86 hw. It can boot from network, pxe, syslinux, CD, floppy or flash-disk and connect to servers using VNC, RDP, XDM, SSH, Telnet, tn5250, tarentella, 2X, NX, Thinlinc, VMWare VDI or ICA.
It's an interesting project. We have a ton of Dell desktops with Windows XP Pro on them that do little else but get used as a platform to run Remote Desktop and we're trying to replace the OS with something more resistant to... well, everything. With Thinstation, we like the concept, but we're not crazy about the interface for RDesktop as it wasn't nearly as friendly as GRDesktop on a few systems I switched over to Ubuntu. We saw where you can type command line switches, but we'd prefer users not have that ability. It also froze on us when connecting to one of our 2008R2 terminal servers. The FreeRDP option wouldn't work at all for us. Anyway, I hope someone looks at this. We do think this project has some promise.
