Using different protocols for "pull" and "push".

Hi.

I wonder if it's possible to setup Git (probably in .git/config) to use 
SSH only for "git push" and use the git protocol for "git pull".  My 
current configuration is:

[remote "origin"]
         url = ssh://user@project.someserver.net/gitroot/project
         fetch = +refs/heads/*:refs/remotes/origin/*

Issuing a "git pull" command results in pulling using SSH (along with 
asking for a password).  Is there a way to alter the configuration so 
that a "pull" will use git:// instead of ssh:// ?
