Thanks for the good help, takethecake!
If you don't mind paying, NFL.com will stream every game live (not just in delay). Their price is half of what it was last year.

Reminder to all, don't post live links in these forums! The NFL copyright folks will swing by and shut down any links they may find. Instead, if you have a link, say so in the forums and then share your link via PM.
