Our JCS use is pretty simple - we cache oql results by the Primary Key.
This does result in a lot of duplicate objects in the cache.

We prefer JCS cache since

- This was the big one - it allows us to flush the cache  - we
need to flush different cache regions at different times of the day to
allow for other inputs to our data sources - we have plugged in a
timer mechanism to work with JCS.
- We are working on building JMX instrumentation to flush the cache
on demand.
- You have the option of caching to disk.

We use JCS as a local cache for each appserver instance though we will be using distributed caching at some point.

I would like to help out - I will ping you offline about that.

Thanks,
Mehul.
