One of the things we spoke about on the kick-off call a few weeks back was to break down this JSR into high level features, and for each feature to have a "lead". Feature leads will be responsible for driving discussion and owning the API (if any) for that feature, and would collaborate with the expert group (using the usual process of voting on conflicts, etc) to build out the feature. Feature leads will work with the overall spec lead (myself) to ensure it all works together as a coherent whole.
I've just updated the wiki with a summary of high level features:
Please take a look, and nominate yourself as feature lead if you're interested in taking any section on. Leading more than one feature is fine if you have the bandwidth. To sum things up, the features we have so far:
1. Async API
2. Distributed code execution
3. Group API
4. Annotations
5. Non-API features (spec only)
6. Eventually consistent API
7. Querying
8. Configuration
