this looks like a fun project, maybe there could be some use among a small circle of friends, for example.
that said, i won't speak for what the market will sustain, but in terms of what we need as a society, i believe we are past the point of needing to invent new messaging platforms. we have email, we have xmpp,(and we have a smattering of other pretty good platforms like WhatsApp, though it is not open) etc. we have mature spam filtering technology built around email, we have TLS, etc etc . this stuff already works. and when it doesn't, we should be working together to improve upon them. there's a lot of work to be done making existing communication more secure, and also things like personal data warehousing of one's communications, etc. etc.
we are not in need of another app (i don't even know what platforms this will run on -- linux? probably not.) that does less than what email did 40 years ago.
