I am looking into the Beta release of Zimbra Desktop client.
We are in the process of evaluating the Zimbra Desktop client for our use.
As apart of evaluation I wanted to know about the source code (open source) and architecture document (How it works in behind with Zimbra server).

I tried searching on wiki pages but could not get the source code and any relevant material explaining the internals.

Can i get some help in both these ares?

It will really help me to arrive at decision based on these 2 areas.

Any pointers hints in these areas will be highly appreciated.

Thanking in advance
