Using SD for beta testing

[lokki]

Ok - I'm about to give this a shot with the following settings:

Copy MacHD to Tester (an existing partition)

Sandbox - Shared users
Smart Update
Copy ACLs

On Complete, Boot from Tester

At this point, I will install the prerelease package with Tester launched.

Before I get going, I have a question about seeing Tester... From HacHD, I can see all the applications installed on Tester, and indeed launch them (obviously under the running environment). Is there any way to utilize this as a virtual environment, sort of like running Parallels for Win packages?
