>>> Well, we can chart that one up to not being the problem.  I suspected it wouldn?t by the nature of the setting label as well as the helper text, which reads ?Allow this backend to receive connections from any IP address on the internet.  NOT recommended for most users.  Use this only if you have secure IPv4 and IPv6 firewalls.?  That tells me that built into mythbackend is the restriction to not accept connections from devices on any subnet except the x.y.z.0 subnet on which the backend resides.  Also, all my frontend machines are on the same subnet as the backend and any machine trying to airplay to a frontend, so that?s definitely not it.

>Now I’m trying to get my backend to run a frontend and see if this is a v29 thing, or a build thing for my other frontend.  When I do run the frontend on the backend, I don’t even get the option in the General frontend setup to enable AirTunes.  Is there anywhere I can look to find the dependencies specifically for AirTunes and ensure that my backend machine has those dependencies?  Seeing as I won’t regularly run a frontend on the backend, I’d like to refrain from adding all frontend dependencies listed in the wiki.

Mythfrontend will not start up if it is unable to load one of the
required libraries.  So the only way to reduce the dependencies to be
installed would be to compile it with all the options off except the
one you want.  But there would still likely be lots of dependencies to
install.
