This is pretty much what I've been aiming for w.r.t the "i32Q9" proposal  
above. I'm still a bit hesitant if this should be actually drafted into a  
as I haven't got any feedback until this point - not to mention that I  
still see
some loopholes that I don't have good resolutions to in the strawman at  
the moment.

I see potential to roll this into a Opera Labs build using Browser  
JavasScript after
discussing internally - but I'll get back to this topic after I actually  
initiate a
internal discussion regarding this matter.

One thing I am a bit unsure about is that pointer.js covers gestures,  
which is somewhat
out of scope - it seems to be a better fit into IndieUI rather than  
touch/pointer events.

What do you think about making this modular so pointer events and indie UI  
events are
in two different modules? (Sadly, IndieUI is still gathering usecases and  
nobody has a
firm idea how big it will be - so making a wrapper module like this might  
be a significant
amount of effort)

That's great - I'd be willing to even fork the code and patch it up to  
conform to
the specification if this actually gets through.
