Actually matrix - the protocol upon which vector and now riot depend - is an open protocol; reference here: http://matrix.org/docs/spec/

And then of course, there are the matrix bridges to IRC, etc. Admittedly although i have been using vector clients AND have installed my own personal synapse server, i have no experience using/supporting the various matrix bridges, so can't speak to their quality.

That being said, if you've ever been curious about re-doing some aspects of IRC for the better, you might want to take a look at matrix (the protocol), and suggest improvements; we all stand to benefit from your (and the community's) suggestions.
