Perl Scripts (vbeta2): http://www.astronomerstelegram.org/SERVENT/ATELstream-beta2.tar.gz.
Keep in mind that the system is now in beta test mode. We expect the main node to experience >99% uptime, but it may come down from time to time for short periods.
The perl scripts serve as self-documentation for the protocol. We encourage developers to create scripts in other languages, and distribute these on their own blogs and website (we are happy to mirror them here, if you let us know where they are!)
