Apparently I need even more caffeine that I first imagined...

If we're talking about networks with that kind of MRC, is it really that 
far of a stretch to require PI space for this?  Then again:  If we're 
talking about that kind of MRC, then I'm assuming ISP A can be coaxed to 
allow explicit and well-defined exceptions on the customer's links.

This discussion started wrt to COTS dual-ISP routers though, as mentioned 
in Ken Chase's message, no?  Where I'm assuming we're talking about 
mom-and-pop operations rather than a $50K/mo business account.
