I've also heard (but been unable to verify) that Engine 0 and 1 line 
cards for the GSR won't be able to take a full routing table past a 
certain point, which I know if it's true is going to cause a lot of 
larger ISPs issues.

I remember when the 3640 first came out you could run a full BGP feed on 
it. That was, however, a long time ago...
