I'll give that a try next time I try MPPP...but I'm still concerned about 
this:

 FWIW, one other serious downside I noticed with multilink was any changes 
 to the multilink interface (including adding/removing members) seemed to 
 stop the flow of traffic momentarily (I remember this being a problem when 
 I used to use ISDN and the second B channel would come up on demand) and 
 doing something like "no cdp enable" would cause the multilink interface 
 to flap.

For this reason, is it best to split up the T1's into more than one 
multilink group and do per destination load sharing with the multiple 
multilink interfaces?
