It has been known for quite some time that Yahoo are trying to make bold changes internally. Products have been shut down (eg. Yahoo Live and Geocities) and it has been rumored that Zimbra has been up for sale for quite a few months by now.

Combined with VMware’s virtualization product line, they can target everything from small business (VMware Server) to large enterprises (ESX). This could be a very serious threat to Microsoft Exchange.
