Using email between 2 developers to keep git repositories in sync

Hello there,

I have been converted to git after reading good things about it. I  
have been using it with a personal project and so I'm familiar with  
the basics.
However I need to share code with a co-developer. He also has a code  
base that I need access to. For several reasons, a shared server will  
not work so I was thinking of using email to send patches back and  
forth.
My question is related to the initial setup and sharing of our  
repositories. Would it be necessary for each of us to make a clone and  
make a tarball of that clone to send to one another before we can send  
patches? The documentation is all based on using a git or ssh server  
to set this up.

Thank you for any insights you can provide me!
