Yes, that's what I thought.

Mmmh, that's not what I thought, that's what prevented me writing a proposal 
as I didn't really know how to put that together.

Unfortunately, no.
Only one student per project but different projects can be related which would 
make student work together.
Such a "parallel" project could be writing some drivers or add a MT API in 
libraries like Qt or GTK+.

About XI1, I suppose it will be dropped once XI2 is finished and implemented. 
So, MT will be for XI2, right ?
