It's quite a difficult problem to solve in general, though it is probably possible to 'cheat' by eg refusing to cross certain boundaries. Tackling this is something I'd like to get on to eventually but I don't have any specific plans on how best to deal with this just yet. There are still quite a few other things I want to implement/fix first, and some of those will probably make splitting by regions easier anyway (eg giving consideration to way and relation distributions rather than just node counts). Having said that, if someone can think of a workable solution for dealing with regions they're more than welcome to have a go at implementing it.
