It would be very useful to have firewalling options on Clueless, this means that if being attacked/DDos etc traffic can be blocked before our lines so that they don't get swamped.
AAISP Could also provide canned policy for people that are too technical. It could be a USP for the AAISP service.
Also support IPv6 (I know you would.) in the Firewall options as this is still quite weak in ADSL routers.
