I am looking for some information from my fellow small/medium business users about the best path to implementing the ZCS for Blackberry. My company is currently trialing blackberry deployment with about 5 devices company wide currently, potentially looking to expand to cover ~20 employees if we can get everything working well with the initial devices.

What is the best route to getting Zimbra to sync with these devices? I know very little about BES, but it seems to be designed for much larger scale deployments than ours. I have also looked into the NotifySync software, which seems to be perfect for our needs, and lists Zimbra compatibility:
ActiveSync for BlackBerry - ActiveSync Compatibility for BlackBerry | NotifySync

We currently use Zimbra Network Pro edition, and I want to make the sync as seemless at possible (cradle-only sync is out of the question). Has anyone else here had success implementing this with a small userbase? What solutions can you recommend?

Thanks in advance
