The compatibility layer will not be ripped out in this round, however.
And that's all we're discussing here...

I do agree, and I think everyone else does too, that V4L2 support in the
apps is a Good Thing. However, it might be that we can get some of those
to work *now* instead of in two years. I'm talking commercial videoconf
apps, Macromedia Flash, etc, which we can't patch and which wont update
very quickly.

As much as I dislike using proprietary apps, in this field the choices
are sometimes pretty limited.
