I need a encrypted and device universal instant messenger

Cancelled

Job Description

I need a encrypted instant messenger compatible with Windows, Mac OS X, and iOS also without ads. I have been trying to find a complete package to do this but have not been successful with the limited time I can dedicate to this. Is there an existing solution that can be easily adapted or would this take custom software? It would also preferably synchronize a particular users messages with their iPhone and either Mac OSX or Windows 7. By the way, I do have a server if that would help this situation some how.
