Thanks very much for the feedback and implementation suggestions.

Yes, this is the new option that could benefit the most people.
I think this workflow would be very fast and make it very easy to have
1 key per project right where you need it:
ssh-keygen -t rsa -N "" -f deploy.key
echo "deploy.key*" > .gitignore
echo "Hello world" > readme.md
git add .
git commit -m "Initial commit"
git remote add origin g...@github.com:breck7/project.git
git push -u origin master -ssh "-i deploy.key"
This probably wouldn't be the option used most frequently, but could
be a neat option to have for both power users and new users.
For power users, I could see this being useful if you have many
projects that all have different keys.
For new users, I could see this is as a quick way to "get out of
trouble" if you are running into ssh problems.
