We do it quite often :-)
We have customers running 2 very loaded T3s in PCs so you are just plain
wrong about that. (see the 110K pps discussion from the other day). I
suppose that the DS3 wan cards you have heard of are not up to snuff. Our
dual HSSI card can run fully loaded quite easily, with bandwidth management
(although I wont say you can have 1000 rules). A 500Mhz box seems to be
able to handle it quite nicely.
You seem a bit biased towards the 7206...even more so than Cisco itself :-)
