Yeah, I don't thinks it's going to be to hard... we have a membership management program we use that does credit card processing and manages the htaccess files for us and we are going to be able to set up a separate profile for this that will let us automate everything... we'll take their management script that runs on our server and when orders come in on that profile, we'll be able to basically have it run an upgrade account script that makes the necessary changes for the user.

I was just hoping someone might have done something like this already and could provide some tips.
