I can see the problem if you're doing everything with EC2.
One point, however:
> You can't switch server hostnames or IPs without potentially affecting your git users.
Yes, you can. Computers should have:
* One or more IP addresses.
* A hostname that is attached to that computer, and only that computer, such as thor.example.com
* Hostnames that are attached to services on computers, such as git.example.com, mail.example.com, www.example.com, and so on. You can change these to point where they're needed, so as to not cause any interruptions or problems for your users.
> And we're haggling over the price of github, here. It's dirt cheap.
Sure, but I'm cheap, and for my setup, it's money I can save, and it just seems weird to pay for something that's so easy to set up.
Say your time is worth $80/hour, and you can get away with the $7/month github plan. Doing it yourself, if you spend more than ~5 minutes/month on admin, it's not worth it.
