You missed what I was getting at. You asserted that only very small ISPs (i.e., those using 36xx-class hardware) are subject to ACL problems. There are many large-ish ISPs still stuck with some amount of obsolete hardware. My point was that while it's easy for someone whose network consists of 10 routers to say "well gee, upgrade already" it's not that easy when your network includes hundreds or thousands of components that need to be upgraded or replaced, to the tune of several million dollars. This is especially true if you're simply upgrading old hardware; in addition to pouring money into an obsolete platform (is that a wise business decision?), the investment of new capital dollars doesn't directly generate additional revenue, which makes it harder to sell to the folks who hold the purse strings. --Jeff
