AJAX e-mail and more

Based on what I am hearing from the folks over at InfoWorld, I would say that one day soon Outlook may have some competition should web apps like this offer sync abilities.

San Francisco (InfoWorld) - A unique amalgam of Linux mail server and open source development platform, the Zimbra Collaboration Suite (ZCS) combines truly integrated e-mail, calendaring, and contacts with a mashup-friendly AJAX client and easy extensibility using Zimlets, which are XML/Web services widgets for initiating content lookups or actions (such as a VoIP phone call) from within messages. Version 4.0 of the suite, announced today, takes collaboration up a notch to document creation and sharing.

ZCS 4.0 allows users to create and edit formatted text documents and spreadsheets, using only their Web browser, and share them via REST (Representational State Transfer) URLs, meaning the server spawns links to the documents — and simple, memorable URLs — that can be e-mailed to co-workers. Calendars and contacts can now be shared in the same way…. Source: InfoWorld
