Re: LDP and comedi

Hi folks,

So unless someone has an objection, I'm going to try to get some folks
over at the Linux Driver Project working on prepping comedi for
inclusion in the mainline kernel.  Unfortunately, it's not likely that
I'll have any time to contribute before the end of the year.

I think it'd be great to see comedi as the canonical data acquisition
library for Linux and built into the kernels of a wide variety of
distributions.  To my understanding, there are a bunch of DAQ drivers
in the mainline kernel that would benefit from a standardized
userspace interface.

Let me know if you have any comments or would like to be involved.

Thanks,

Tabish
