Ok. I was thinking along the lines of a hardware firewall/dns  pointer/website blocker for  between the cable modem and wireless router. Has anyone looked at the configurability of the raspberry Pi that's been discussed?
Thanks, Mark

You don't need two cards.  Just about anything running some variant of Linux or *BSD should be able to be configured to cache DNS responses and forward DNS queries to whatever upstream nameservers you want to use.  Some distributions will make that process easier than others, but the box itself could most likely even be one of the tiny "gumstix" models (about the size of a typical USB key) and still be plenty for what you're likely to need.

The more important thing is what hardware do you have easily available to you, because I think that may constrain your choices more than anything else.
