This isn't something we will have the time to implement, but we'd certainly be happy to look at a pull request that adds GAE/CapeDwarf Channels as another transport option in ErraiBus. We'd be looking for:
- A working implementation that doesn't interfere with or complicate deployment on a standard Servlet container
- Automated tests that demonstrate Channel communication working (probably using the GAE development/testing library)
- API documentation on any new types as appropriate
- A new section in the Errai Reference Guide that explains how to set up a GAE/CapeDwarf app
We've got a good track record of working with community members who take the time to submit pull requests with new features and bug fixes. Close to 100% of pull requests have been merged. We know people put a lot of work into them, and we treat them as such!
