Only things I can think of right now would be the additions of:
Cacti (Historical Stats)
FreeRadius (WPA/WPA2 Enterprise)
MoBlock (w/ nice interface to keep out known baddies)
PPTP Client & PPTPConfig (bound to second LAN for privacy)
Snort (See bad things going in and out)
BTW Thanks for the USB drive option for saving the config!!!!
Most important thing I want is to know the rule that cause a logged accept or reject in the log.
