MattJSyndace, having the libraries available is one thing - but with just a few hundred KB of RAM, it's going to be very tough
SyndaceMattJ: Sure, it's going to be challenging. But I'd imagine half a megabyte of RAM should be fine for "just sending messages". It gets interesting when additional XEPs come into play.
SyndaceMaybe COM8 comes up with a little POC soon :)
SyndaceBut I might be lacking the XMPP knowledge to estimate the RAM required to create and keep a connection alive.
