Absolutely. From the application standpoint disks connected to Sun Rays are real 
disks, only not located under /dev (each terminal has its own device root).

Two things to keep in mind...

One, we might choose to use partitioning implementation other than libparted on 
Solaris, compatible with the original at the D-Bus level.

Two, there will be a separate backend for Sun Ray, because Sun Ray software is a 
separate product from Solaris and not (yet) opensourced. We expect that the 
backend will ship as part of the Sun Ray software bundle, and dlopen'ed by the 
Solaris backend.
