Sounds too focused on the technical side. XMPP is imho already a bad branding (not pronounceable, not memorizable) so we're not bringing much accessibility by coining another techie term.
Imho if we want XMPP to gain traction over WhatsApp users we need to present it as a user-focused, no-hassle, easy-to-use option.
But maybe you're targeting the IT community?
