IMO you should look at the discussion on a numeric_adaptor by Barend Gehrels and some draft code mentioned in
http://archive.freebsd.se/?ml=freebsd-questions&a=2007-05&m=11343770
to get some idea of the problem and a plausible framework which might include 'BoostsOwnBigInt' as an alternative to GMP
etc.

PS But you should also be aware that another xInt project is being discussed on this group.
