This is excellent news!
I have campaigned to get XODE support in an editor for over a year now with no luck. ODEEd
showed the most promise, even has a plugin system making a third party XODE plugin a possability, but the programming language is foreign to me, and the developer appears to have lost interest. Levent Bayindir is working on an open source viewer/editor written in Java that reads and writes XODE, however he has been slowed down by university study. Your annoucement is welcome indeed, your product looks very useful.
Please keep us posted KuRi! If you have any questions or critisisms of XODE, then please email me. I use it extensivly, however there are some areas (in the spec) which I don't and are a bit untested. Do you plan to implement an XODE importer as well? This isn't nearly as important, but it encourages interoperability between tools.
Once XODE support is added, I will link to you from this page
I have found XODE very useful for my own project, and invaluable in a team project I worked on where I created the simulation engine, and a designer created the game. He could tweak the XODE model to his hearts content without needing to contact me, or recompile his own code. Anyone who's used ODE can probably agree that you do end up doing a LOT of tweaking...
