I have two good reasons about not to use e-mail nor web to timestamp.
The first is LSSI (LSSICE), the new spanish Internet law. It's worse
than DMCA in certain aspects: my e-mails and web navigation can be
accessed WITHOUT a judicial order. That's worse: they must be logged by
the ISP and maintained during a year. The second is simply not to
overload Internet. The e-mail you sent me has EIGHT "Received" header
lines. That means that the e-mail put load into, at least, eight e-mail
servers and all routers between them. In my scheme (of course it can be
improved, and that's the reason i proposed it here) the timestamp
service puts load only on the timestamp server and the routers between
And about real time stuff, imagine a public administration, like
Ayuntamiento de Madrid (Madrid council), that must timestamp a lot of
documents with Enter and Exit dates.

Again: let the user NOT TO USE E-MAIL AT ALL. After that, It's a good
idea sending and timestamping only a digest. I said in a previous mail.
I'll write a new feature-proposal/protocol-proposal taking that idea I

What do you refer? Sorry, I don't understand that completely (remember
I'm not english native speaker).
