The one I ordered a birthday card from Zazzle for but which hasn't 
turned up yet... :-S

Seriously, Zazzle boasts that you can have your order within 24 hours, 
but that's only actually true if you line in North America. For the rest 
of the world... it takes rather a long time. :-( I wish they would set 
up a facility somewhere in mainland Europe...

Ah, I see.  There are so many Jamies' in the world.  But hey, it sounds 
like you've got at least *one* friend.  Actually, though, I know you have 
more than that. ;-)

Seems a lot of companies operate that way.  We have a similar experience 
when ordering DVDs from amazon.co.uk as well.

And not just DVDs (hit send too soon).  Just got a copy of the Uxbridge 
English Dictionary, and it (actually surprisingly because we ordered from 
a US site) also was sent via Royal Mail from the UK.

And I kinda promised that if I ever have children... well, there'll be 
*another* Jamie in the world. ;-)

Meh. There are people I sometimes speak to on teh interwebs. But human 
beings that I can actually go hang out with? Now that's a tiny list. :-(

Really? I usually find Amazon to be quite good...

Yes, exactly. That, and all the other things you might want to do (like 
be behind a NAT) that OpenVPN doesn't handle.

Note that SSL and TLS are both technologically the same thing. The 
difference is in provisioning. That is, it's SSL if you start the 
protocol dance as soon as you open the port (because you're talking on 
port 443 instead of port 80, for example). It's TLS if you open the 
connection, do some negotiation, *then* start encrypting, such as with 
BEEP or Secure SMTP or anything else that has a "STARTTLS" command.

I thought I saw somewhere that OpenVPN *does* work with NAT, but IPSec 
doesn't. (Because NAT involves packet modification, which IPSec is 
obviously designed to prevent.)

No, what they said was that if you want IPSec to work with NAT, you had 
to exclude the IP addresses from the hash calculation with a 
configuration. Since OpenVPN never even offers the opportunity to 
include the IP addresses, it's "simpler" and therefore more secure.

Huh?
