I think coping with different client and server versions is also going
to be an interesting issue - possibly more so than in other
applications where the product is releasing more slowly, or where the
client and server are kept in sync.  It's already something we have to
deal with, and handle reasonably but perhaps not optimally, and since
we're trying to have fewer roundtrips  either asking for the server
version up front, or bouncing the whole request may be suboptimal.
