Well... So far Cisco and Juniper have been able to piggyback their use of TCAM resources with what's available in the marketplace. From what I've picked up from reputable sources, we're pushing the limits, and Moore's law does not appear to apply to the rather specialized market of humungous TCAM chips.
TCAM is not the only lookup system suitable for packet forwarding lookups: Juniper have been using RLDRAM II since 2007 (FCS of m120). And Cisco have started using RLDRAM in the ASR1000 packet processing engine. I'm not trying to understate how difficult this sort of thing is, btw. Packet forwarding engines are hard. Nick
