brennok, have you considered using something like SyncToy or similar for your situation? It has its own set of pros/cons like WHS data duplication feature, but for the need that you describe, it should be considered.
You mention using WHS 2011 and it would be a good solution for you assuming you need the features it offers like backups for your PCs, remote access, etc. Going with WHS 2011 would allow you to retire your existing WHS and stick with a single machine to do all of your backup/server duties.
