Perry,

I think your answer to number 2 is incomplete. Once the original principal database has caught up, you can failover and 'return' the original principal to being the principal server. We do this every month when we apply Microsoft patches. Fortunately, we have low transaction volume, so the catch-up period is mercifully brief. Can't say what would happen in high volume environment - could end up always playing catchup and never resynchronize?
