I wouldn't, I'd expect an email from the buyer. Is there a rule of
thumb way to check?

Would be most interested in commentary on this.

Well I hope 'not SO small':-). Am not worried. Given the small number
of buy operations and infrequency of Paypal downtime, concurrency of
these events would be remote.
But I do worry about some nasty intercepting and cocking up any part
of the process from 'the buy page' through to emailing a 'key' and the
subsequent download. Not infecting buyers is the point.
