msva-perl should be able to report it's running version number
currently, the msva reports its supported protocol number (1) so that clients can know what to expect in case the protocol changes.
It would be nice for it to also report the specific version of the package, just as a piece of advisory info, which clients could choose (or not) to present to the user.
