One additional question I subsequently thought of:  Wouldn't this be an 
invalid scenario though to have in a single linkset?  One of the 
assumptions that I made was that you have one point code associated with 
a linkset/set of signalling channels, not multiple codes associated with 
a single signalling channel.  That sounds almost like an STP type 
configuration...

I completely understand that you have this problem and are attempting to 
find a good way to solve it.  It's just that I never presumed that such 
a scenario might exist for a non STP box.
