Airbnb API

Need a webbased front end to single login into multiple airbnb accounts and respond to bookings, give offer bookings, modify bookings, view potential customers, send email followups and view consolidated calendars without ability to modify payout information. Basically a front end to manage other airbnb accounts without access to payment information. One login that logs into multiple airbnb accounts without entering passwords. Passwords are encrypted and saved somewhere else. Install on centos, cpanel, prefer you use Ruby on Rails.
