So moving the mouse on the lock screen without unlocking switches the
<show/> off? That would seem to be wrong, but note that the presence
<show/> state is really a quality of implementation issue (ie, you can do
it "Wrong", but it's still interoperable).

As I say, the RFC doesn't say much about this, and certainly not *anywhere*
in RFC 6120, which concerns itself with the low-level stream handling. 4.6
is to do with TCP sessions going awry, and nothing at all to do with user
The <show/> element which controls the "idle", "away" etc state visible in
presence is covered in RFC 6121 §220.127.116.11, and doesn't discuss anything more
than syntax and semantic meaning. XEP-0319 has a bit more on idle, but
still doesn't say what "interaction" really means. I don't think it needs
to, but still, a cat walking across a locked keyboard probably shouldn't
