If you haven't already, I'd encourage you to have a look at the
FFI that's being used for the Hugs/GHC system. The spec is available
via the HaskellDirect home page
http://www.dcs.gla.ac.uk/fp/software/hdirect
It supports static&dynamic call-outs as well as call-ins.
If this FFI proves to be generally useful, perhaps someone
might propose it (or a variant thereof) for H2, who knows.
