Two days ago Apple released this announcement (emphasis mine):

Mac OS X Server v10.4 “Tiger” will also ship on Friday, April 29. The next major release of Apple’s award-winning, UNIX-based server operating system, Tiger Server integrates 100+ leading open source projects and standards-based software applications and more than 200 new features including native support for 64-bit applications, ideal for high performance computing; iChat Server to deploy secure instant messaging within an organization; Weblog Server to publish and share weblogs (blogs); and Xgrid to turn a group of Macs into a virtual supercomputer.

With the widespread use of Apple products in education I can't wait to see the changes this new(?) technology will lead to. Apple always seems to be leading innovation in the use of personal computers .... did anyone really need another reason to get a mac? ;-)
