It can. The hoops to jump through involve writing delta editor
callbacks, doing validation on the state of the repository, and --
most importantly, and where most of the work is -- driving the delta
editor to apply your changes to the repository.

Here's an example (in C):

  http://svn.collab.net/repos/svn/trunk/tools/examples/svnput.c

(Also cited as examples by cmpilato and rooneg are: 'svn import', 'svn
copy URL URL', 'svn mkdir URL', 'svn delete URL', etc.)

Can you describe exactly what you'd like the API to look like, and
provide pointers to how this looks in the other binding APIs
(e.g. Ruby, Python, etc.)?

I might be able to put something together.

As Mark mentioned, implementation of these APIs will be need-driven.
Personally, I'm definitely interested in seeing such bindings emerge,
and would certainly be willing to help anyone interested in writing
some patches.
