Zimbra - Pricing for Zimbra Collaboration Server on-site, Zimbra Hosted, and Zimbra Mobile

Is this correct?

To clarify, if the network edition PRO version is purchased, all add-on modules are available free, such as blackberry, outlook connect, archiving, mobile, etc?

50 seats of netwrok pro is $1750 USD?

50 seats is 50 accounts whether it is accessed via outlook or mobile or blackberry?

I submitted a query via "contact us" but have not heard back in several days.

If this is not in the right forum feel free to move it... Apologies.
