Now? It was in production use 9 years ago:
http://xapian.org/history
It's improved quite a bit since then too - notably the protocol has been
rewritten and is a lot more compact.

It should work. Whether it will be faster depends a lot on the speed of
your network and how slow the queries are on a single box, which depends
on the collection size, amongst other things.
Unless you have a lot of documents, with modern hardware you are
probably better off scaling by adding more clones of a single local
server. But I don't have a lot of directly comparable data points
so if you try both, I'd be interested to hear.
