Goodness me. Erlang? Session balancing? Reporting to Graphite? I just love how the VerneMQ github .md starts with ‘an extremely simple and lightweight’ and then shortly after has a long list of very much not simple nor lightweight features. I guess if one is digging into all this it probably all starts to seem terribly mundane after a while.

Looks like we have WebSockets in 5.1; all the tests seems to be happy in TestRunner at least.

AFAICT it’s 2000 lines of JS, which may actually count as simple. It would help if I read JS of course, which I don’t.

Hey, I have an idea - Marcel! Isn’t this a perfect thing for one of your students to tackle? So much stuff at HPI seems to be working with things across the net. Just imagine the things that could be done with a squeak mqtt  wotsit to talk from Etoys or NuScratch to, well, whatever.
