Well, this can be a pretty deep topic for a monday morning :-)
In my experience, the approach and solution for "remote mirroring"
really depends on two things:
        1. are you doing disaster recovery, versus mirroring diversity?
        2. how far apart are the mirrored devices?

Without answering those questions first, you will risk a suboptimal
solution.
