I'll put in my vote that the userspace library API should be held to the 
same standards as the hypervisor ABI.
In reality, there won't be more than a dozen guest ports to Xen (for 3.0 
at least).  There will likely be dozens of tools written that use the 
userspace API though.

I'd be happier linking against it statically.  I really like having 
simple code though.  What does everyone else think?
