The OpenGL bindings should be usuable, but I haven't tested yet. I just
hope they will be included directly into SDL soon. And you're right,
translucency is a lot slower than transparency, which can heavily be
accelerated (via MMX instructions for instance).

Well, nothing can amaze me anymore, you know ;)
Changing the graphics on the fly would be a huge operation. I can well
see the potential of putting an additionnal layer to simulate night, or
weather effect - that would be applied after the map rendering. But as
for modifying objects directly... I don't know. I'd say it's too far to
tell whether it's reasonnably possible or not.

Yeah, and with just a bit of Python ;)
