Unfortunately and iOS port is not in my plans, due to both lack of time and also funds for the iOS developer program which costs about $100 per year.
However my plans are to release both the plugin and the application with an open source license (not sure which one) on GitHub at some point probably around September or October (maybe earlier). Along with this I will try to provide some documentation on the protocol to enable people to use the plugin with other applications on other platforms.
One thing to keep in mind for anyone interested in using the plugin with another remote application, is that the new version of the plugin/remote will use JSON instead of XML.
A small status update, is that the search and queue functionality is almost done though I got some issues with the implementation that I have to fix in the near future. I have to get a few things done and I will probably get out a beta version, maybe I will upload it to Google Play, since it has a really helpful system of issue reporting.
