Ad Network for Forum Signatures?

[LyNHS]

I just wondered if there was anything PPC based that could work in signatures based in Forums and Online-community based Signatures?

I'm obviously NOT going to include it on BHW, but I was just wondering perhaps it could be used in conjunction with Xrumer ... obviously a lot of planning and tweaking would have to be done lol ....

Thanks for your help in advance!
