eBay ecosystem grows

There is no doubt that over the years an entire ecosystem of companies have developed around "the eBay economy". There are companies that will help you list items, companies that will help you win auctions, etc. Today eBay signed up HP to compliment their digital photography offering. How long until you see other big name companies offering their online services directly to eBay customers? For every digital gadget sold through eBay there is probably some type of complimentary service offering that could be sold.
