Dion Almaer’s post about App Engine with Ruby, Python, and Perl led us to ask the natural question we ask around here: “What about Comet?”

The short answer is, not yet really, based on this little bit from the App Engine documentation:

Some features impose limits unrelated to quotas to protect the stability of the system. For example, when an application is called to serve a web request, it must issue a response within a few seconds. If the application takes too long, the process is terminated and the server returns an error code to the user. The request timeout is dynamic, and may be shortened if a request handler reaches its timeout frequently to conserve resources.

For those hoping to build the first hot Comet App Engine App, you’ll have to wait. Per Dion: “Remember guys…. this is just the beginning.”
