Thanks to this post
I finally got motivated to work on events support.
Attached is a test version of my XBMC2 plugin that adds event broadcast
The event support is not finished and I expect there are bugs, so please if you want to test it use a backup copy of your EventGhost config as I expect I will change stuff before the feature is complete.
The events feature will need to be activated in the XBMC2 plugin options.
Unfortunately there seems to be a problem with repeated events in at least the two versions of XBMC I have tested, but XBMC from 2009 on my XBOX don't have the problem. If you always get 3 events when there should be one try the option "Event workaround" in the plugin options.
I would appropriate any feedback especially if you get error messages.
Edit: You need to activate events support in XBMC using the HTTPAPI: SetBroadcast action in the Experimental folder, a 1 or 2 in the parameter edit field will activate it.
