I recently sent out an email announcement of development on org-babel
which should provide a unified backend for evaluating source-code
contained in org-mode blocks.  If org-exp-blocks is using org-babel for
it's source-code evaluation the ability to interactively evaluate blocks
will come for free.  This would be my preference rather than
implementing a new code-evaluation schema for org-exp-blocks.

I suppose that this would assume that org-babel is accepted into the
core of org-mode (for it to be a requirement of org-exp-blocks which is
now part of the org-mode core).  While this would be my preference, it
is certainly not my decision to make, and I honestly haven't given it
much thought up until this point.

Thanks -- Eric
