I might have some bandwidth to help out, although it's likely not until the end of July. The best bet for anyone who wants to help on Jython dev is really just to hang out on the IRC channel, #jython on irc.freenode.net, or attend a sprint like the one upcoming at EuroPython. Then you can rely on the Jython developers as a community, not as an individual.
One possible starting point for an array interface is http://www.unidata.ucar.edu/software/netcdf-java/v2.2.17/javadoc/ucar/ma2/package-summary.html; it seems well supported and capable of handling large data sets. For the Numpy side of things, Daniel Lemire maintained JNumeric, which was started by Tim Hochberg, until about 2002, this could be a useful starting point for how to integrate into Jython: http://jnumerical.sourceforge.net/index.html.
Lastly, Leo's reply to your other email is correct: it's best to write everything in pure Jython, just calling to (or calling back from) Java as necessary. Based on my experience, I would imagine you could get most of the functionality done this way, and it would help you determine what you need to write in Java directly to get desired performance and/or compatibility.

developers around here that would be interested. I can't personally
work on this for the short term, but I'd be glad to help with any
questions you might have.
Check out the new SourceForge.net Marketplace.
It's the best place to buy or sell services for
just about anything Open Source.
