[aerogear-dev] AG Security questions

Hey everyone, I'm looking at http://aerogear.org/download/ and am somewhat confused. Some questions about the Security part of AeroGear: 1. Is there a reason why OTP are separate libraries, instead of a namespace on the existing AG libs? 2. What's the difference between "Security Providers" and "Alternative authentication methods"? 3. Are Hawk and Java-OTP server modules? What about iOS-OTP? That sounds like another client lib? I hope I got this right, if not, please enlighten me. Thanks, Hylke
