Lotus notes and iCal

[jab]

I have just started reading about Zimbra. Looks like a vibrant community and a great development team. But, I have some significant knowledge gaps.

Here's what I would like to do: use Zimbra to sync between lotus notes and my .mac iCal acocunt.

My office uses Lotus notes. Is it possible to use Zimbra as a go-between for my work calendar to be synced to my .mac account?

Sorry if this has been answered, but I've done a little reading, and I'm hazy on this.
