Actually Tom is running a page where he shows double spends detected by his
node or relayed by mine (there are only two nodes in this little detection
network currently), and it does show double spends that occur seconds,
minutes or even days apart.
Regardless, whether that approach helps or not is off topic for this
thread. Let's all hope it does and discuss the details in some other
thread, or on the pull request.

Yes indeed, if you want to do high frequency trading then every millisecond
counts and you probably don't want to rely on watching transactions
propagate across the block chain. For inter-exchange traffic this BIP would
probably be useful. I've been talking about the consumer case.

No, I expect there to be many kinds of trades where dispute mediation is
unnecessary, e.g. when I buy a drink at Starbucks or a burger at McDonalds
the chances of me wanting to charge it back is basically zero. Same for
sending between people who know each other, large corporate transactions
where the threat of a lawsuit is more useful than mediation, etc.
But for transactions where third parties are needed for dispute mediation,
yes, I'd expect there to be a handful of well known trusted names for the
majority of such transactions, and then a long tail of specialists who only
mediate e.g. purchases of rare Aztec artifacts or other things where a
generic company might be easily fooled.
