Startup Zimbra releases open-source Notes alternative
From InfoWorld: Startup Zimbra releases open-source Notes alternative
Zimbra, the open-source startup that lured Scott Dietzen away from his former job as chief technology officer of BEA Systems, has released a beta version of its enterprise collaboration software. The San Mateo, Calif. company bills the software as an open-source alternative to enterprise collaboration products such as IBM Lotus Notes or Microsoft's Exchange Server.
Sounds like it's more an open-source alternative to Exchange than Notes, in that it appears to be more focused on email/calendar/scheduling as opposed to an application development platform. While I generally like to see new ideas like this get a chance to survive in the market, I have my doubt about this niche. With Notes and Exchange holding such a dominant place in the market, it will be hard to get traction. Enterprise software such as this is an area where you want to have assurance the company will be around for the long run. But you can't get customers until you show success in the marketplace, and you can't show success in the marketplace until you get customers.
Of course, the same's been said for Firefox, too... :)
