Please note that I am working on creating a much improved V4L infrastructure to take care of such things. It's simply nuts that v4l drivers need to put in all the plumbing just to be able to have multiple instances. In particular, all these limitations on the number of instances should disappear (unless you run out of minors).
If you use vivi with a large number of devs (for example, 128), you'll run out of minors, since we currently have only 64 for video grabber. Due to the videodev limits, in fact, we can allocate "only" 32 virtual devices per driver.
Even with the changes on V4L infrastructure, vivi driver still doesn't do the right thing if you use a large number of devs.
I'm currently fixing the "vivi" driver and adding some notes on it about the current limits.
