Hi there! It has been a while since there's been significant progress
with Aalto -- mostly it's just because of other competing things going
on, but part of it has been due to:

(a) Core blocking (traditional) parser being feature complete, up to
complete Stax 1.0 compliancy, as well as Stax2 Typed Access API
implementation (there's still DTD handling to add, Stax2 Validation
API, but those are bigger undertakings)
(b) Apparent lack of interest for non-blocking parsing

But during past week I have had multiple contacts from developers who
would be interested in finding a non-blocking XML parser. Since Aalto
is almost there, I would be interested in completing minor missing
pieces.
To do that, what I really could use is a simple use case where to
plug-in such a component: ideally, a library, app or framework that is
accessing data using NIO (directly or via something like Netty). To
have something I could actually test with Aalto in non-blocking mode.
While I could write a toy test app that does not seem right -- it's
better to handle a real use case.

So... anyone with something I could use? Or willing to take to
collaborate on getting something like this done?
