I'm not sure what kind of tool you want to see here; the only thing i 
can think of is
a way to manipulate the v4v firewall in dom0.

From a client side PoV, this is up to the guest kernel to expose the 
capability.
For example on linux, the idea is to exposes it is using a new socket 
family, so that
everything is handled by usual syscalls (socket(2), recvmsg(3), 
sendmsg(3), connect(2), listen(2), ioctl(2), ...), and the userspace 
doens't need any library,
and specially just a trivial change to already written code that use ip 
socket without changing any semantics.
