Description

Integrate the Z-Push library into Horde. Provide the ability for Horde to provide over the air synchronization of email, contacts, and calendar data to devices such as the iPhone/iPod Touch, Android and any other system supporting ActiveSync.

Rough list of issues/todos in no particular order

Need to implement ghosted properties / SUPPORTED tag. Currently, all data on the server is overwritten and replaced with only what the PIM sends. It's possible for some PIMS to ghost contact and calendar properties so that only the supplied tags are changed, and missing, ghosted properties are retained on the server. When a PIM supports this, it sends a SUPPORTED tag with children representing the NON-ghosted properties. The absence of the SUPPORTED tag would indicate that any property not transmitted should be handled as a ghosted property.

Need to implement better error handling, sending back the appropriate STATUS code for failures, instead of just sending back a generic HTML message that would probably never be seen by the user anyway.

Another AS implementation in PHP, though we can't use it due to the license, there is some good information there for the taking.
