Switching zones takes a very long time though, be warned about that (entering/leaving a guild hall or apartment or using a teleporter can take minutes in such a setup rather than seconds).
If you have a multicore machine, this is easily fixed by setting the different clients to use different cores. I use a program called WinAFC (available both in 32 and 64 bit versions) to do this for me automatically.
