	Assuming you don't have IPv6 already (though if you had, you presumably
wouldn't be writing this mail :)  ) get yourself some IPv6. You can grab
a tunnel from sixxs.net for your computer, configure it (takes all of
perhaps 10 minutes) and now you can communicate with your computer
wherever it is - behind NAT notwithstanding.

	I use it to make sure my laptop has the same IPv6 address whether it's
connected at home, at work, over a 3G modem or via a wireless hotspot -
if I'm online, you can ping6/ssh/scp/rsync/whatever to
mylaptop.example.com (made up dns name) and you'll get my laptop.

	Hope that helps.

	Best regards,
