Can cmvision run with multiple cameras on the same robot?

Hi, I have the cmvision package working with two different camaras, but when I try to bring up both of them simultaneously, the initial process (doesn't matter which one I bring up) dies.

To resolve this, I tried renaming the node. Both processes will then come up, but I only get message data (/blobs) from the instance I launch first. (I have two launch files)

Any idea why this might be happening and if there is a workaround?

the nearest I can tell, the answer is no. A workaround is to add another machine to process data for the other webcam.

per comments below, ~~workspaces~~ namespaces enable this

Can't you run both instances under different namespaces? With some suitable topic remapping, you should then be able to provide each instance their own input and output streams as well. Running multiple instances is actually a common use case.
