Or better yet, I think I could set up a m0n0wall outside the main one that 
will simulate our ISP gateway - that way I should be able to turn on the 
Captive Portal on that inside interface and have all requests that exit the 
edge m0n0 redirected to the Captive page.

I'm going to do some work and testing on this during this week.

Thanks Chris.
