Okay, here's a patch against the head in CVS that implements 
mt_setPostCategories().  The rest of it is untouched save for a couple 
of nits that I fixed.  Also, config.xml in the tree should probably be 
changed to set <category-root-element> correctly for this to work from 
a checkout.

This is not well tested at all and it's not likely to get a lot of 
testing by me but it allows me to do what I wanted with NetNewsWire 
which is create a new posting with categories.  The weblog in NNW needs 
to be configured as a Movable Type system.  I'll be happy to fix any 
bugs in this but as I said, I'm not likely to find them myself.

Not related to the syncato implementation, it's kind of an unpleasant 
little protocol.  Not very flexible and a lot of overhead for not much 
gain over GET/POST and friends.  I guess the gain comes from it being 
in fairly widespread use.  Still.
