I agree with J0kerz. Mobile anything. Apps, vids, mobile chat, etc...
Dude, hit google. Think you will find one very promising resource in the first 3 posts. I just googled and found a perfect candidate in 2nd position. When dealing with tech niches, stay on the tech blogs. Those fools know when products are coming out of beta. Out of beta = new to the open market. And if it a product made it passed beta and it's 1st-2nd round of capital acquisition, you're looking at what could essentially be an unmanned cash-register at Wal-Mart during Black Friday. i.e. - filled to the top with possibilities.
Most often, when a tech firm clears 1st-2nd run, they've spent the seed money on development and VC presentations. That means any new money is being spent on marketing, and scalable solutions. Affiliates = marketing. Now go get some of that marketing money!
