Huh? What would this help with?

You do realize that Linux supports this today. You plug in a new
device, and it automatically loads the proper driver based on the type
of device it is. The kernel and userspace already do this just fine.
And Linux does _not_ support out-of-kernel drivers easily, and we do so
for a very good reason. You need to get that driver into the kernel
tree and then everything will be just fine.

No, it's educating the developers that they should not be doing this :)

OSDL is trying to start to provide this kind of functionality (the "get
new gizmos to coders" part), but usually companies that know what they
are doing, already do this. It's rare that if a company wants to have
their device supported on Linux that they don't get people volunteering
to help them out.

No. You do NOT want to duplicate the nightmare that is the whole "Works
on Windows" branding that Microsoft currently has in place. I could go
on about this if you really want to know more...
Just put a simple penguin on the box and say "works with Linux". I've
seen it all the time on things ranging from scsi cards to USB flash

Come to FreedomHEC http://freedomhec.pbwiki.com/ and all will be
And yes, we do seem to have a ton of Linux jobs here in Portland...
