create an e-commerce widget that formats vertically for inclusion in blogs and on web sites. (leftnav, rightnav) a good place to sell you e-books, t-shirts, etc.<p>make it free to use and pick up a % + transaction fee. hook it up with amazon and others with affiliates programs for those without things to sell.
this is kind of neat. if i could easily throw up something like this on the right side of my blog where visitors could purchase books that I'm recommending I would definitely do it.
