Who knew? Apparently eBay has
an incredibly extensive developer outreach program. Check
this out to download an SDK for your favorite programming platform.
The one thing that I wish I could do on eBay is subscribe to a query as an RSS feed
so that when a new item matching my criteria is put up for auction, I get notified.
I would think it would also be useful to subscribe to bid activity on items in my
eBay list.
