Really easy .... It is possible, but there may be things you have to address. For example, one approach would be I make my purchase and receive a username/password I can use at an alternative site. That would work basically as you describe although not with a redirect. The user just needs to login - which is an extra step you/or user may not want.

Extremely complicated .... One problem I run into is that a cookie (what keeps the user logged in) can't ... easily ... go from one domain to another. They are exclusive to the domain and can't crossover. So when a user does something on one site, they need to login (create cookie) to use another site. You could do more extensive programming to work around this and avoid making the user login at each domain that they did not register/pay at.
