Except that it can't be merely wire protocol. They're remapping the
commit, copy, delete, move,branch, tag, and merge operations of one
source control into the other. That's..... not directly comparable,
especially the tag operation, which is really designed to be much more
locked down than Subversion has by default. In theory, I suppose you
could lock it down to emulate the git "thou shalt not touch me" model.

And unfortunately, there are Subversion usage models that simply don't
map well to the standard trunk/branches/tags layout, such as matching
simultaneous tags for source code and/or binaries of multiple parallel
projects in the same repository.
