HTML5 / Java - RDP / RDS Gateway - repost

I am looking for a developer to write an Java/HTML5 RDS Gateway to run over http/https. Site needs to allow all devices and browsers (HTML5) to be able to connect and operate efficiently (no delays, freezes, screen painting delays). I have looked at other products that have similar features. Below is a list of features that is required: Windows OS's - RDP Virtual Channels (lpt, com, usb, clipboard, sound mapping, drive redirection) - RDP Virtual Channels needed for [login to view URL] software - Simple printing (opens print job as PDF on client) MAC OS's - RDP Virtual Channels (lpt, com, usb, clipboard, sound mapping, drive redirection) - RDP Virtual Channels needed for [login to view URL] software - Simple printing (opens print job as PDF on client) LINUX OS's - RDP Virtual Channels (clipboard) - Simple printing (opens print job as PDF on client) Mobile OS's (Phone/Tablet) (Android/iOS/BlackBerry/etc) - Screen based cursor/keyboard (similar to that of TSplus) As far as the web interface/login in concerned, users should reach a login page that only requires their username/password. The web server will be running on a Windows server OS so the authentication should be based on AD group membership. After login the website should initiate the best connection method available based on the users OS and Browser. HTML5 gateway will run from a server within the network and will need to be able to RDP to an RDS 2012 (load balanced) farm.
