Open Source!
Well, you’ve been waiting for the big webOS announcement, and today we’ve made it. This morning, HP announced that webOS will be going open source with the resources of HP behind it. The Developer Relations team is very excited by this announcement and what it means for the future of webOS, and for you, our developer community.
HP webOS Dev Center is probably of interest to a lot of people here. Get the SDK, etc. and start hacking.

It appears to me that development is supported in C++ and JavaScript.

Seems odd all this says "Palm" all over the place, but maybe not. This is supposed to be based on a Linux kernel plus other stuff developed by Palm originally.

It all sounds interesting, but I don't think there's an x86-targeted build and I don't know what platforms are actually supported yet.
