Yes, I have tested the archive with std::vector and it simply works.

I guess it works also for any collection, which is supported by
Boost::serialization framework.
The magic is in the <boost/serialization/vector.hpp> header, not in the
archive itself.

For any primitive type always the same xdr_* function is called, so (by the
design of XDR)
it does not matter if the caller is 32 or 64 bit (nor if little/big endian).

The only issue I have discovered so far is if you want to serialize
OS-dependent type, i.e. pthread_t,
which in case of Linux can be <int> and in case of another OS can be <void
*>. This is however
difficult to handle and at the same time easy to avoid.
