I'm using S3 to host files generated by podsync, and it would be great if podsync can be executed like a crawler, which generates the data and then exits.

That way,

• I can avoid exposing another port of my server to Internet
• podsync does not need to be running in background all the time (I'll use cron to excute podsync and transfer the data)

I know I can use firewall to block access to the port exposed by podsync, but it's always nice IMHO to have less firewall rules and running-in-background processes.
