Why no progress in the Directx plugin?

[AllenSword]

A window pops up when I try to download and says I need to enter a username and password, but the one I use for this site doesn't work. Oh, and I don't expect this thread to change anything Diddy Kong, I just want to see what people think, and to get answers as to why opengl is more of a concern than directx. And I did not know that about the opengl plugin(the ability to work with all OS'es). That rather impresses me. So, my guess by that comment is that a lot of the users here are using linux or mac?
