Ok, not to be a nay-sayer in the crowd, but is that store window thing really going to work?
I mean, he can copy the HTML for the store window and pop that on any web page in the world, but I believe all of the pointers will still be pointing to eBay...
I may be wrong...but if you ask one of the Auctiva folks, I'm sure they'll probably tell you the same thing...
