I *do* like anyone comment the format ! But if the comments are "we were here
before so shut up" of course it's totally stupid and useless.

Well, maybe they don't code on Windows but we code on Linux. So I don't see a
problem if they want to stay in their own world.

Yeah, I can foresee a lot of fun if they insult the coder who want to help them
all the time...

It's not dangerous for open source. It may be dangerous for us, maybe. As Xiph
would say, we were there first :D

I can predict no success in trying this. But I'm not against it.

Yes why not. But we don't really need to work with them to make a DSF for them.
The problem I can is : we don't have the resources to help them !

Ever been bitten by a dog you want to carress ?
Do you think we can come with a deal : we support your format, you support ours
? One of them being a scaled down cousin of the other...

That would be a wise idea, yes. Especially because it would open the door to
different codec API on different OS that deal we the same basic data.
