We just released another Google Wave robot and gadget – It allows to search for auctions and collaborative shopping on ebay.com. Wave participants can share auctions & information with contacts in real-time thanks to automatic queries by the ebayBot against conversation keywords. The eBayBot gadget can detect products and return inline auction and product links or a custom full auction browser.

By now, everyone has probably heard of Google Wave, the innovative communications and collaboration tool that’s been turning heads since it debuted last May. With its rich feature set, it definitely seems to have a promising future, both for consumers and the enterprise. However, the thing that struck me most about Google Wave is that it’s not just an application, but a powerful open platform.

This means that APIs can extend its functionalities even more, in ways faster and more creative than if Google decided to keep it inside a walled garden. Since its launch, thousands of eager developers have been given an access pass for testing, and the company has held events to sustain interest in the platform, as well as showcase what the community has done so far. Here are some of the more enterprise-friendly extensions under development today from the Google Wave gallery:

Doing some exploratory thinking about the possibilities opened by Google Wave, I came up with this very early idea of something that could turn out to be pretty interesting. In explaining it, I’ll assume you’ve watched that huge 1h20min video they have about it (it’s worth every minute, but there’s an abridged — 10min — version).

Motivation

People have been doing code review through email for ages. It’s the easiest, dead-simple way of doing it. Just add a post-receive-hook to your repository and make it email a diff of every new commit to a mailing list. People answer to that email, inlining comments where needed. Great, you say. But… It’s not 2.0. Bummer.

Continued from part 3: extensibility.
Google Wave in many respects is the ultimate collaboration tool. It can be best compared to Wikipedia but instead of striving for encyclopedic accuracy people can work together to strive for their own outcomes. In doing so they can add all kinds of content, including gadgets and robots that can give a helping hand.
