I don't think there's any particular reason for it to be closed, and in any
case the interactions via xenstore, and the kernel driver sources, are open
for anyone to take a look at. A lot of Citrix stuff does end up in the
public trees -- it may just be that noone has considered this, or it needs
clean up, or something...
