I set 'ip tcp path-mtu-discovery' on all my boxes by default, and the 
vast majority of them still assumed 516 or 536 MSS.  I tweaked the 
transport options in a few routers and that brought up the MSS.  It 
looks like the code on one of ME6524s won't let me set that option 
though so I guess an upgrade is in order.
