Hi,
I might not be in the States, but could fly down. I felt compelled to reply as I have more than a Decade's worth of experience in Web and Database Design as well as 4 years in Mobile. During my 4 years as a Mobile developer, I've made a system that runs on XML ( HTML inclusive ), that can do the following : Bluetooth, Encryption, Compression, Location, Video & Audio players, to name a few functions. It sounds like a good fit? Feel free to query how the above mentioned functionalities are achieved....
Cheers
JB
