Mm i see yes , your pathfinders code
to handle streaming would be very cool.

I think full source is needed to have a look at the navmeshing
but okay i believe more detour/recast features could be integrated when
he decides to update the engine itself i read that on the forum some features
were planned on the roadmap just not sure if its true..

I also noticed the non navmeshed pathfinder may work from a image file
where colored pixels can represent non walkable areas
maby this would be more usefull by image minipulation and building
a array of images of your map by pixel representation..
