Sirs

I have a new project with very strict affiliate requirements.
Affiliate Gyms will send emails out with promotional details about the product.
The link will contain a code identifying the gym that issued it.
When a sale is made the customer will be locked into that gym for a defined period.
Should the customer pick up a leaflet from the gym, that leaflet will have a code which will identify the gym.
Failing that an ajax style selector identifying the gym would be presented to the customer.
As a last resort the customer can just buy anyway!

So the store software must:

1. Maintain a database of affiliate gyms (not websites but perhaps including them)
2. Issue affiliate email and print codes
3. Present the customer with the 3 stage affiliate code sequence described :
NOT email then type code
NOT type code then select box
NOT select box then jst go ahead with NONE selected
4. Lock customer into gym for defined period
5. Recurring sales with recurring billing
6 Gateways preferably including Worldpay or DPS
7. Affiliate and sales admin accessible pages to track sales by affiliate
8. Inventory control

Can Ubercart do this and with which plugins?
