If you mean a host that supports rewire, then yes. But I don’t believe it can actually host rewire connections, only slave to them.
If you are talking about Podium then I am confused about your remark. Podium can act as host for other ReWire slave applications (such as Reason). Podium can not slave to other ReWire hosts.
.. I am so terribly sorry, I got it the wrong way around. Thank you for correcting me. 🙁
