i am very much in favor of sharing and exploring these sorts of things, however, in this case, as mc68k mentioned this is not freeware. it is software betas meant for distribution to beta testers and is covered under apple's NDA. discussion of how to obtain such material is not allowed in these forums.
and as a less moderatory note, you should never run such software as your main operating system. this is not distributed to the public for a very good reason (besides apple liking its secrets), it is not finished and could screw up your machines. if you feel you are experienced enough to test out betaware you should also be experienced enough to know that you should run this on a spare computer, drive, or partition and be damned careful to prevent loss of data. also if testing betaware is something you enjoy you should contact software developers with your feedback and let them know you would be interested in beta testing their software in the future. it might sound improbably but i think you woudl be surprised how open a company will be with their betas if you provide good feedback.
all that being said, please refrain from discussing the acquisition of materials such as these through anything but the legal routes. a public forum is not the best place for this and is not allowed on this particular public forum.
