svn without local copy

I'm in this kind of situation: i'm working with a remote developer on a cakephp website.

He works on a local copy (php etc..) and updates a staging server. I usually do directly the edits (mainly css and text changes) on the remote staging server because I can't run a local copy of the website. What do you suggest for a SVN environment without running a local copy on my machine?

I had setup an account with Beanstalk to do 1-click d开发者_JAVA技巧eploy from staging to production and automatic ftp upload of changed files on staging server when the developer does the commit.

My question is, what could I do to commit my changes as I'm modifying directly the files on remote staging server?

thanks

The remote development server could be showing a working-copy. As you work there, you can write the svn ci command whenever you want to commit a new version. You also could programme a cronjob to refresh the server working-copy to update to your partner's changes.
