I'd suggest writing it with OpenGL instead of DirectX, as it's cross-platform. If I find a decent .NET library for OpenGL, then maybe this will be done. But as I wrote in my previous mail, portability is not the most important concern for me - in the past I tried to make Kosmos 1.x run in Mono on Linux and it kind-of worked, but there were a lot of issues with this, so basically I gave up. Kosmos 2.x is even more difficult in this regard - it uses certain 3rd party libraries which are Mono-unfriendly. The additional problem is speed - I can make this thing run fast on Windows by optimizing the code. For an interactive mapping tool this is essential - slow map drawing just kills the purpose of the app. But if the portability is the main issue, then the speed looses out (unless large chunks of code are written separately for each OS).
