On the subject of SunRPC, the implementation in glibc in fact does allow
you to replace the basic send/recv operations, so it would* be possible
to write a back end which talked over (say) gnutls.

On the other hand, XML-RPC has mindshare, has a nice enough C library
(xmlrpc-c: http://xmlrpc-c.sourceforge.net/) and supports SSL**.

Rich.

* Or so it seems from looking at the code, but I'd need to write a test
client & server to be sure.

** Only checked this on the client side, haven't verified that the
server side can support SSL yet.
