Not as far as I know.

In fact it sounds like almost all software based efl engine. In my
opinion, you will just need to write an evas module engine for the
graphic part that use the evas software engine and ecore_vnc library
that retrieve the event and send them with ecore-input. Then just
another small piece of code will be needed in ecore-evas so the link
with both library will be done.

It sounds like a really interesting engine to me, so if you need help
during don't hesite to poke me. But anyway many people can certainly
help you here or on irc #edevelop channel.
