> SPICE was specifically designed to be a display protocol for a KVM virtual machine. Most remote display protocols have two pieces... a client and a server. SPICE has three... a client, a server, and a qxl device driver provided inside of a KVM virtual machine. It is probably possible to take the SPICE protocol and adapt it to work without the qxl device driver... but no one has done that yet.

Google created some project, I forget the name, forked from FreeNX I believe. No Machine is working on version 4.0 of NX and supposedly will be releasing a beta in the not too distant future. Some time ago they posted a lot of information about NX 4.0 on their website and it seems to rival SPICE to a certain degree... but that remains to be seen.
Google's NX implementation is called 'neatx': http://code.google.com/p/neatx/

NX the protocol is open already.. :)
Nomachine's NX server product is not..
