Hi John,

I think you have proposed a lot of very interesting projects. Here are 
my comments on some of them. However, I'm afraid that I cannot commit 
the time this year to be an offical GSoC mentor.

This sounds very useful athough the devil is in the details. Are you 
thinking about mapping the Store api 
(org.apache.derby.iapi.store.access.*) to some smaller api which is 
easier to port?

10.6 introduces custom types (see DERBY-651). There is substantial 
support in Derby for being able to compare and index types which 
implement java.lang.Comparable--however, that support is disabled right 
now. Enabling that support would be a smallish, focussed, useful task.

I imagine that there are some existing compatibility test suites out 
here. It would be interesting to understand Derby's compatibility with 
other databases. This sounds like a task on which a GSoC student could 
make good progress.
