Hi !
I tried the beta version of your plugin with json support. It works very well for me !
I tried using action and also from within scripts and it works great !!
I also tried the "send message" action without any flaws, using XBMC dharma beta 2 on windows.
The only thing missing now is the receive event part, maybe using the broadcast functionality of XBMC but that way you get minimal information like playbackstarted, ended, stopped etc.. Sometimes you get the name of the files but not everytime..
I use some python xPL lib to broadcast these kind of event from XBMC and use your plugin to get more information, using the best of 2 worlds !
Also, thanks to your plugin, one can add all the information on xbmc from a customized eventghost web interface, to incorporate it nicely to their home automation ui !
Thanks again for your work !!!
