Hello everybody,
For those who would like to use Syphon to stream video into Capture there is a tool called CITP Tool from Krautscheid Medientechnik, originally built to stream Catalyst Media Server mixes to CITP. The new version (v2) can stream several video sources into Capture using a Syphon supporting App or any area which is shown on your desktop as video source. CITP Tool supports streaming from several computers into Capture. For streaming CITP Video content from different computers an instance of CITP Tool needs to run on each computer. I have tested it, streaming video from Millumin and Qlab to Capture Atlas and it works very nice.

All the best,
