that’s the point:
AFAIK it doesn’t exist a thing like this but IMO in it’s absence the user community will be limited to computer scientists or computer science students, hobby home programmers and beginners have no access and remain excluded as they already desparate during the install process and to upload the most simple sample programs.
As BCC is open source and already supports Java, pbForth, BrickOS, NXC, and gpp C/C++ it just would have to be customized and adapted to Mono. It’s even running on Windows XP, 7, Linux, and Mac (CMIIW).
A downsized Mono IDE with a Sketch-look-alike IDE of course would be fine, too.
