I think Eclipse RCP is an exciting part of the Eclipse story. The ability to build rich client applications with a component model that allows for dynamic updates of new features and patches is pretty compelling. In fact, I think for ISVs and open software projects it makes an excellent platform for deploying software.
We have lots of examples of Eclipse RCP applications listed on eclipse.org but I know there are many more examples that have not been listed. If you are building an RCP application and want to be listed send an e-mail to news@eclipse.org. I would also like to get screen shots of RCP applications that I can use for presentations. Feel free to send them to me ian.skerrett at eclipse.org.
