IMHO XMPP is far more architecturally sound and not driven by buzzword-development.

Ouch, LFS of all things… That’s harsh.

I’d be surprised if MS Windows came with a C compiler, tbh. But it’d be a bad choice for non-technical people anyway; it’s not exactly a user-friendly language…

Python would’ve been my choice, but maybe also consider Lua (a lot of games include it as their scripting language, which might be an easy selling point for people)
