Initially I used the Vera-XBMC-Plugin from mrw292 and chixxi, which is much more advanced than this plugin, but I had some issues:
[ul][li]I have the Vera Lite so cannot afford to run too many complex plugins, due to the memory constraints[/li]
[li]Persistent TCP based control was unreliable and caused my Vera to lockup sometimes when the XBMC device went to sleep[/li]
[li]I did not need 2-way control with UPnP event subscriptions, in my setup[/li][/ul]
Perhaps this is useful to someone. I use it extensively with my RoomRemote plugin for IR Control of multiple AV devices in one room (GitHub - pigsty/vera-room-remote: Vera plugin and associated Arduino Yun sketch for IR control of media and lights in a room).
