I think so, see my post of last Thursday replying Joe Van Andel.
The attached example concerned Vtk Python objects, but I would try
the same approach for Boost.
There may be a few gotchas, though:
(1) sip generated modules do not use Python's standard way of importing
other modules' C-API's. I solve this by patching sip's output.
(2) it is probably impossible to mix the inheritance hierarchies of
sip-generated and boost-generated classes.
I have a vague recollection of a thread about mixing SIP and Boost.
