I guess the management issue is going to be versioning the protocol.  If
the protocol is just a direct mapping of vir* calls and structures then
you'll quickly end up in a situation where even the smallest change
requires you to upgrade the world or old versions have to be maintained
indefinitely.

That's not saying I don't like the idea.
