Just a side note: professional gamers typically think that 100 mouse
events per second are a bit too slow, they prefer 200-400. I don't
really know whether this makes a difference, and we don't want to imply
any upper limit anyway, but if we ever should have an estimate of an
upper limit, I'd say we should rather go for 1000/second.

Humans are still slow, though ;)

Extensible: definitively. I would even go as far as claiming a
hierarchical format would be of great value.
ASCII/XML: doubtfull in my opinion.
