Review HN: SyncFu - Group Buying Component

Hi everyone! I've been playing around with the idea of group purchasing, and I'd appreciate your comments.

http://www.syncfu.com

SyncFu is a tiny js extension for websites, allowing group purchasing through reservations. Reservations are paid (micropayments) via cell/cc, ensuring some reliability for sellers.

The concept is very simple, demand forecasting. Discount codes are generated for each reservation and item, so after the item meets a deadline, that can be reused within a shopping cart for instance.

To a seller, this means volume sales, while for customers - lower prices.

I see this as a versatile tool, most likely used in promotions, organizations, pre-ordering etc. Got some ideas?

It works over http/https, hosted on heroku. If you wish to test https:
