If you use Microsoft Media Foundation video source in Plus then you can choose between devices by the device ID parameter.

Note that cheap cameras often have poor drivers, which may not allow to connect multiple devices to your computer at the same time.

Yes, sure, you can send any number of image streams. In PlusServer configuration, you need to create a `PlusOpenIGTLinkServer` element for each image stream (set a unique `ListeningPort` and the correct `OutputChannelId` for each).
