In the Linux desktop world, Telepathy serves a similar role: it's a unified daemon that handles all account connectivity (XMPP, Irc, Sip, Jingle, Aim, MSN, &c), and other programs talk to Telepathy instead of making their own connections. Telepathy and Tenyks are both communications services.

D-Bus is used to talk to Telepathy, which fills the role ZeroMQ plays in Tenyks.
