Well, actually, all I had been thinking was that if a common language
is feasible (and for simplicity's sake I hope it is), that language
might need to represent a superset of what each of the backends need
-- containing markup that might mean nothing to the vm but be
important to lightning, and vice-versa.  Presumably such markup would
be fairly rare, but I suspect there may be situations where it could
have a big impact.

Agreed.
