[PD] Approaches to "show control" platforms

Hello everyone,
I am very interested in show control, and I have been dreaming about
developing a complete set of open source show control software since years.

I think that Pd could be part of a backend, but it lacks some features of a
sturdy "real" programming language. Namely: a unit testing framework,
multi-threading, etc.

I think that the ideal GUI for a show control application should be
Web-based. It would allow it to be distributed. I have already done such
distributed Web GUI applications in the past. I am very satisfied with it!

I am not sure how we could find some money to develop such a set of tools,
but please let me know if anyone is interested in thinking about this
seriously. Let's start a mailing list and get our brain thinking and our
hands writing code!
