Their web-based management system is HTML5 based. The configuration profiler builder is a clone of Apple's iPhone Configuration Utility, and is quite complete. There are many management features over and above the standard within the iOS5 apis such as location based services, secure mobile browser, secure content locker, an iOS app sdk (provides management libraries to embed within your app for additional functionality)
AirWatch also manages Android, Symbian, Blackberry and Windows Mobile devices.
AirWatch offers several deployment options. You may purchase the software (requires Microsoft SQL, among other infrastructure), purchase an appliance, or use it as SaaS (i.e. hosted by AirWatch on their own servers). They are friendly to resellers and the site may be skinned with your company's theme.
The system allows for multiple "Location Groups" and "Locations". You can use these to set up a multi-tennant system where each "Location Group" has it's own LDAP based authentication component & each group pays for its own use. This is useful for resellers.
