I think a Boost licence (option) bigint that Boost code can just use without
causing licensing difficulties would be very useful. described some of
the issues.

Would Barend Gahrels (see his comments in the conversation)

like to mentor a student to push his numeric_adaptor project along?

(Or would Kevin Sopp like a student to finish his promising effort - preferably
in a numeric_adptor way that it can be switched).

But it needs to be very well documented with lots of tutorials and examples.

If one can switch it to use faster, but possibly license-troublesome underlying
engine, so much the better.

An even bigger can of worms! Let's walk before we try to run ;-)
