If they allowed me to embed their system into my site to provide "smarter" message boards, I would gladly pay them a set-fee/month.

They don't need to care how I monetize my sites.

[Sadly now they do not allow this in any way]

You can't embed, that's true. You can pay a set fee and run your own however: http://stackexchange.com/

Not as part of another site. ie site that has more than just stack-exchange. (And they don't allow iframes)

Now we know what you've been up to.
