No, but I have been thinking about this as well. It might be a nice capability to have, so long as the regulatory spectre continues to discourage some vendors from disclosing information about their hardware. At least such a scenario seems less grey w.r.t. GPL compliance. Still, I would not want to put much effort into a project that distracts from development of fully open source drivers. But I think the performance of such a solution would be sub-optimal enough to discourage full reliance upon it. And the plus of having a userland binary driver versus no driver at all might make it worthwhile. What is the situation that makes this interesting to you? Thanks, John -- John W.
