Something has always bothered me about Novell's Mono project.
What bothered me was the nature of the project. Novell isn't building anything competitive.
And on Preakness morning I finally figured out the analogy. Moonlight is a lead pony. (Shown is Mutak, a thoroughbred racing now at Keeneland, with its lead pony. From the Louisville Thoroughbred Club.)
A lead pony eats like a horse, lives around thoroughbreds but is not itself a competitor. Its main purpose is to ride in the post parade, calming the thoroughbreds down.
That's Mono's purpose, not to produce competitors but lead ponies. Moonlight isn't a Silverlight competitor. It's a companion program. If you have a Linux machine, it will let you run Silverlight files. Maybe. Someday. Sort of. Why don't you just get a Windows box?
And here's the point. You don't build a community around a program like Moonlight, any more than you go to the betting window and bet a lead pony. The source may be open, but to say such a program is open source is like calling a lead pony a thoroughbred.
This is a corporate project, a sideline, and of interest only if your shop is dependent on Microsoft but might have a recalcitrant Linux user somewhere on the back stretch.
