Connecting domain to google app engine without google apps

Question

Actualy, It\'s a couple of questions:

1. Is it possible to somehow avoid registering google apps if I just want to connect google app engine applications to non-n

Answer 1

Here is a couple of answers:

1. No, Google App Engine uses Google Apps to manage domains. See the Deploying your Application on your Google Apps URL article.
2. Yes, if you are a School or University as explained here. If you aren't, why don't you just go for the Standard Edition?
3. Yes, for a couple of domains and a couple of GAE instances, you'll need a couple of Google Apps AFAIK. But this shouldn't be an issue as the Google Apps Standard Edition is free. No. As pointed out by Nick, you can add multiple domains to an Apps account as aliases, then map them to different App Engine apps.

Edit: The 3rd answer has been updated with the input provided by Nick Johnson in a comment.
