In case anybody’s interested, it was pretty easy getting the Twisted Core running on the ConnectPort X4. Once we gathered all the dependencies there were only about 10 lines that needed to be changed to avoid OS-specific code (the library thinks it’s on a linux box with signalling available). I get a few unhandled exceptions at startup (haven’t tracked them down yet) but I haven’t seen anything that crashes the program.
It’s about 500k in size and a little slow to get started, but it’s definitely worth the convenience of having Twisted.
