Yes, and I actually did it a while ago. But there are some minor parts
of pydolfin that don't work with a general ufc, which I plan to look
at soon. And if you want to use FFC and SyFi in the same application,
there will be some issues with degree of freedom mapping.

I'll report back when I have it working. We'll make a new release of
SyFi once we've cleaned up some details and the documentation (it has
been way too long since the last release...).
