Of course, all of the software I write runs on Linux; that's the beauty of standards, and of cross-platform code. I don't have to run your OS, and you don't have to run mine, and we can use the same applications anyway!
On the other hand, there would be some value in different folks getting together to share expertise and technology; but to the listener, it wouldn't necessarily seem like a single station in the traditional sense.
Software Engineering might be science; but that's not what I do. I'm a hacker, not an engineer.
I think Linux is a great thing, because Linux is an alternative to Windows, and because, of all the operating systems that are at all relevant today, Unix is the best of a bad lot.
And when the time comes to replace the O2 I have today, maybe my next machine will run Linux.
Mostly I use the O2 as an X terminal, however, running my apps on Linux and displaying remotely.
I think Linux is a great thing, in the big picture. It's a great hacker's tool, and it has a lot of potential to become something more.
Linux is only free if your time has no value.
