Finally got around to submitting my netfilter hacks which add network quota support. Took longer than I would have liked to make it patch-o-matic friendly but it's done now so I'm just waiting for Harald Welte (who incidently has an almost identical Geek Code to me) to put it in. It is intended for use in a commercial internet billing system but given the flexibility of netfilter I'm sure people will find plenty of creative things to do with it.
- Cable users in Australia for example might want to keep themselves from going over the 3Gb limits imposed by the greedy telcos (esp Telstra, which is doing it's best to keep Australia in the dark ages).
- Hosting centers and ISPs may want to impose traffic caps based on agreed credit terms
- Educational institutions may want to exercise some control over students (the network equivalent of /dev/null for 1's and 0's)
- Network administrators may want to limit certain types of bandwidth (eg quake, streaming media, etc) or traffic to certain machines/MAC addresses/subnets/etc.
