I had come to the same conclusion when trying to think how to implement
msgs tests in a 'hobbit' way.  So it seems that hobbit needs some manner
of 'push' mechanism. Of course this is just pushing configuration, but
since you are talking about a 'push' mechanism what about pushing files
too ?  Though this option may be cosidered a security hole. But this
would be nice for pushing out updates.  Whether it is a full Hobbit
client update, or if a particular script/test needed to be pushed out
and updated.

Pushing out files could be a configureable option that can be
enable/disabled.
