Thanks Tom. The Surinder Singh route sounds very interesting. If I was to go and work in, say, France (I speak a bit of French) over the summer university break, taking my partner with me and getting married before we left, would that be enough? If so, what would her standing then be - could she remain indefinitely? The page you linked talks about a lot of factors I wouldn't be able to fulfil (children in the country, strong links, etc etc).
Thanks Tom, will do.
