Question spanning Disk Director, OSS, and True Image

Before upgrading to the most recent versions of TI and DD I would like to post some questions that I did find solved when studying the manuals. Basically, I want to run two XP on one machine, each system on a separate drive. None of the systems should be able to see the partitions of the other system. However, for performance reasons, I want both systems to crosswise use some partitions on the disk that they are not residing on. And, I want to "install" the second XP thru Universal Restore (DI+) of image files. In other words:
I have two computers, let's name them ONE and TWO. TWO is intended to reside on the 2nd disk of ONE. I want to achieve the following setup:
Disk 1: Partitions ONE-C, ONE-D, ONE-E, (..) , TWO-G (Page), TWO-H (Temp), TWO-I (DI Secure Zone) - and
Disk 2: Partitions TWO-C, TWO-D, TWO-E, (..) , ONE-G (Page), ONE-H (Temp), ONE-I (DI Secure Zone).
System ONE on Disk 1 should not see any of TWO's partitions, but be able to access its partitions on Disk 2.
System TWO on Disk 2 should not see any of ONE's partitions, but be able to access its partitions on Disk 1.
So: (1) Can OSS be set to see both drives and allow each of the systems to only see their own partitions? (2) Can I run True Image on (old) computer TWO and then have the images machine independably restored on disk 2. (3) Will OSS then detect and activate system TWO.
Would be really great if someone could advise me here.
