It's hard to know for sure without trying it, but I'd expect it would be
faster to serialise in C++ if only because you'll have to make more
Xapian API calls from python to do the serialisation from python.

No, it's internal to the library (at the moment at least).

I've thought before that it might be nice to provide serialisation in
the API for all classes where it makes sense (e.g. it does for Query and
Document, but probably doesn't for Database) especially since we already
have the code for many of them for implementing the remote backend.
Being able to store serialised Query objects would be useful for an
alerting system for example.
