That sounds like fun.  

I think we don't support multi-pointer X, but if you have a big touch table and multiple users, it's a similar scenario.  So I suppose you can drag and pinch multiple items at once, but cannot give keyboard focus to multiple items at once, right?

Is it possible that xinput 2.2 could work with this hardware, if someone wrote the X driver for it?  Because we already support that kind of multi-point touch without any plugins.  But maybe the tagged objects are too special, not ordinary touch points.

Can you tell more about your application to use this?
