Looking at <http://subversion.tigris.org/issues/show_bug.cgi?id=2263>, the current suggestion there is to implement multiple-locks-in-one-request by POSTing to the me resource. The POST handler is already implemented --- it slurps the request body, parses a skel and calls a callback with the remainder of the skel --- and it has one user already (implemented for both ra_neon and ra_serf).
Given the above, implementing #2263 does look like a straightforward exercise. However, it would require a custom skel-based request format for the body. Couldn't we use the ra_svn lock-many request for that? And, if we could... Couldn't we take this one step further and write a POST handler that, essentially, acts as an ra_svn proxy --- grabbing a POST request from the network and passing it unmodified to ../svnserve/serve.c? --- So, this may be an absurd conclusion, but I would feel ridiculous implementing a skel-based solution for a problem that we have a known-good ra_svn-tuples-based solutions for.
