If You use the feature with DTrace like tool, You can operate
it in parallel. This is just a idea. I know Sol10 has chroot or zfs
which behave like jail. What I'd like to say is that you need not
insist on just DTrace you can develop original one.

I think so. If you develop the DTrace like tool, you need the resources 
at least
equivalent with DTrace team, I guess. If you do, your develop team will make
any action to get a resources.
