Yes, but I'm not sure how you'd manage failover in that situation then.

There is not currently any way to accomplish that, unless you do it in 
the database itself. If your database supports updatable views, then 
each server could actually be connected to a view that provided only the 
desired rows out of the master table, and the failover process could 
rebuild the view for the new 'active' server. It'd be a bit ugly, but 
not horrible.
