No point in DX10 just yet -- wait a couple of years, get the vast majority of the machines on the planet working first
I got my Eclipse environment all set up. I pulled down the 1.1.4 source and will add the d3d changes in my development environment. I disconnected the source from the SVN just to be sure I don't foobar anything, though I'm pretty sure I couldn't commit anyway. I haven't used ANT much before, but from what I've seen so far it rocks, a lot. It's definitely something I will learn more of. I just had to mess with some Windows environment variables and it works like a charm. This is probably as far as I'll be able to get this week, but I think it's a good start.
