    via BoingBoing:

    An AT&T researcher has presented a paper detailing a technique for counting the number of hosts behind a NAT box (a router that shares a single IP address among multiple machines). Very interesting stuff -- there's a lot of work being done in P2Pland on traversing NATs and allowing machines wiht "private" IP addresses to participate as full-fledged Internet hosts

    it is discussed on slashdot in detail

    some header through NAT can be used to effectively count hosts ..... by the way it is UNIX problem when ipchains/iptables are used as a NAT solution.

    ISTR that Bills software is not affected, amazingly.

    Why do eircom have a problem with this anyway on the solo package, where you have a 3gig cap?

    Ah, i see now, just read that article & comments on slashdot, still think you should be allowed do whatever you like if you stick to the cap tho.
