No. Thanks for the pointer. After a first look, I suspect their cash
rely on some online server to prevent double-spending?

(With Brands' system (without the "observer" extension), double spending
is also detected at the time coins are deposited at the bank. But then
it's possible to distinguish between the case of the same coin being
used twice in the payment protocol, which is the payer's fault, and the
coin info somehow duplicated between payment and deposit, which the
payer has no control over).

Regards,
/Niels
