I would have thought so, except that everything else in DRb works
*except* passing an object by reference.

I've spent a whole day testing all kinds of dRuby client-server-remote
things and they all work fine... until you try to call a method on a
remote object that's been passed by reference.

I don't understand how (or if) objects passed by reference would have
such a different TCP/IP packet.

Can anyone imagine what might be blocking this kind of activity, but
not others?   I've been poring through the drb.rb code for an hour
now, and can't figure out what it might be.
