[TYPO3-english] Payment for access rights

[Kim Holberg Andersen]

Hi,

I have a client who wants to sell access rights to a computer based 
training program, granting the fe user ex. 3 month use of the system.

So, it should work like this:

1. The fe_user register and pays for a key on a webshop (tt_products)
2. The fe_user is send an orderconfirmation with the access password to 
the site by email.
3. The password expiries after the given time.

Is there any ext. or combination that could be used like this?

Thanks in advance...

Kind regards,
