I do not understand why things need to talk AllJoyn instead of talking CoAP or MQTT.<p>If AllJoyn is solving a problem that using CoAP or MQTT does not, then great, but it won't be a PHP unless it's completely opensource and I can run every part of it on my own machines.<p>This may be the case, though it isn't clear if this covers all the required software<p><a href="https://git.allseenalliance.org/gerrit/#/admin/projects/" rel="nofollow">https://git.allseenalliance.org/gerrit/#/admin/projects/</a><p>The AllJoyn site doesn't seem to have any obvious links for installing and running the whole thing on for yourself.
