Fwd: Shared memory between Dom0 and DomU

Hello

While waiting for some help, i continued to google about this topic.
In fact, i want two distinct process (one on the Dom0 and the second one 
on the DomU) to be able the read or write in a share memory.

Many post are talking about granting permissions or grant table.

I'm sorry if my question is a bit stupid. Where would i start to be able 
the test those grant permission?
Should i need to write an external program or should i modify some Xen 
source codes?

I really have no idea about where to start.
I'll sincerely appreciate any idea. Even one stating where to start.

Thanks in advance!
