Some days ago, George Wright announced on #nx that he just had committed a new qtnx, based on the nxcl libs. Qtnx is an open-source Qt-based NX client, and it looks like development on it is rolling again 🙂 It is now based on nxcl, developed by Seb James.
In fact, George is now working for a company on a NX server (and client), their web site is desktopondemand.com. The client is GPL-2, and should support most NX features (including 3.0 shadowing). Of course it is still under heavy development, but you can find them as -9999 SVN ebuilds in the NX overlay. Just run:
# layman -a nx # emerge -av qtnx
I hope this one will soon join nxclient (binary-only, but latest NX features) and nxclient-2xterminalserver (GPLed NX 1.5 version) in portage
Btw, the ebuild is currently marked x86, as these are the arches I test NX on. Drop me a line if it works on ppc (it should) or other arches
