I have a longer term plan to make a next generation K12Linux that throws out LTSP entirely in favor of the fully Open Source components of kvm and the SPICE protocol. What is the status of SPICE in Fedora these days? Will remote USB ever be supported without the non-open source shim library?

Spice is pretty 'mature' by Fedora standards in that it's been there for two whole releases now. =) It's the default for newly-created VMs in F16, and it works very nicely for 2D graphics and sound. 3D passthrough isn't done yet. Hans de Goede has a very shiny set of improvements to USB passthrough he's working on which build on SPICE, which have USB 2.0 support (so more devices work and transfer speeds are way better - he has webcams working at full speed inside a VM) and a neat optional feature where if you plug a USB device in while the VM window is active the device goes straight to the VM, but if you plug it in while any other window is active, the device goes to the host.

What shim library do you mean? Hans de Goede did some recent work on redirection of USB devices over the network for use with Spice/Qemu. This was also integrated into Fedora 16, some bits (for integration with libvirt) may still be missing though.

You can read about this on Hans' Blog:

I am not aware that any kind of closed library is needed to use this. Instructions for building from source are available from Hans' Blog.

This is good news. SPICE early 2010 when I last looked at it required a closed source library for USB redirection. It sounds like SPICE is now ready, and I will work on the next generation K12Linux soon. =)
