Why not? The xenstore libs are available in most distros, even if you
are running in domU.

In addition libxenstore supports for being used statically for cases
where you are deploying into generic/unknown environments (such as for
use in a guest agent). As do the xenstore-* tools

Static binary that used in compile in debian, does not work under centos...
And us i see - implement for domU xenstore proto not too hard... it writes
to xenbus C struct with 4 fileds and read response...

This cool if program written in C, if the program in Lua or something else -
for that you not need to use C functions, all operations may be done on
native language Lua/Go.
P.S. I''m partialy write Golang xenstore bindings, that uses C xenstore
libs.
Now i''m try to rewrite it to use only /proc/xen/xenbus.
