So, the question comes back to: non-free or not distributable at all? I think the case of KDE sets the precedent, and it's not distributable at all. Aside: Would "doing the impossible" be a "field of endeavor"? :) On Mon, 23 Oct 2000, Barak Pearlmutter wrote: > > These are linux-specific k

The modifications would probably be so great that you'd have a copyrightable work in and of itself. However, as Marcus has pointed out, the algorithms are the sticky issue and that would be enough to consign it to non-free if it was distributable at all--Debian-bsd seems to be back from the dead,

Hi, the package rtlinux contains RTLinux. This is a real-time layer below the Linux kernel to provide a Linux operating system with real-time capabilities. In the documentation of version 3.0 of RTLinux a patent is mentioned (US Patent No. 5,995,745). This patent covers the underlying principle
