Some highlights from today's investigation into secure RPCs (a topic
which I want to bring to a close as soon as possible).
* TI-RPC was suggested as an alternative to SunRPC. The available
library has licensing problems which may preclude any integration into
libvirt.
* SunRPC over IPv6: tested and working
* Either xmlrpc-c or Curl (which it uses for HTTP connections) cannot
manage to do persistent connections, which makes XML-RPC very slow. I
haven't yet got to the bottom of why this isn't working, since Curl
certainly ought to be able to do keepalives.
* Some performance numbers which you can take with a large grain of salt
are available here:

The other issues are written up in the above document for your browsing
pleasure.
