Software switched routers have little pressure on fib limitions. For a certain class of application the software switched edge router is in a much better position to accommodate fib growth than a device with a fixed sized cam. 

I dunno about that; there's some papers floating about which look at
trie type FIB representations which note significant savings in compressing
FIB to unique entry set. Less memory, less comparsions, less nodes, etc.
Rather interesting stuff.

Not saying that they couldn't benefit from it, however on one hand we have a device with a 36Mbit cam on the other, one with 2GB of ram, which one fills up first?
