Feature request:a flash private sales like jetsetter

Can you please see if this project can be bulit into a site like jetsetter.com which is a hybrid between flash deal and hotel bookingn? The key feature beyond normal hotel booking features for a site like that are
- multiple hotels
- show valid participation period on calendar for each hotel (the current setting for this module let users to search their checkin/out dates but for this type of site, it should show upfront the availability period)
- merchant login to manage own room type and availability
- limited period offering (like groupon)
- price calculation based on number of consecutive days booked

Thanks in advance
