Thanks Etzion.

Yes you are on the same track as me.

An unmapped Elastic IP will cost $3.65/month, which is a significant amount
in comparison to the numbers I'm looking at skimming, so you are probably
right about using a no-ip address.

Finding the instance IP is a matter of a trivial "curl" call to the right
URL, and no-ip can just use the current update requests source address
automatically anyway.

The next step would be to automatically identify idleness of the
application for automatic shut down.

Would people in the audience here see themselves using such a service (to
fire up your server) if it was offered?
