Yep, its this, but i test today and i dont get any message in the XBMC. When i was using Eden, long time ago, i remember to put this to work. Every OSD that i send from Vox was showed in the XBMC, this is particularly useful when we are using the XBMC with Wasapi, since in this way we cant get sound from Vox, so i just use the OSD to show some information when i need.
I am planing some nice commands with this, i will make a video later. Do you know that we can send a picture and a text for the XBMC and then a notification will pop up with the information, right ? Let´s say that vox its monitoring some web cam, alarm system or door bell, when any event of this systems happens we can send a message for the XBMC with the picture of the web cam or a information about what sensor was activate or even a message informing that are someone ringing the doorbell.
For me, the best thing will be have Vox and the XBMC working together with the Audio Wasapi setup, but this will not gonna happen, since the XBMC block any other program to use the audio.
