There should be no problem with multiple writer sharing of
devices across domains. Of course, make sure you're using a file
system that expects this (e.g. GFS) otherwise you'll trash the
file system for sure!

Xen 1.2 supported this too, but the control tools deliberately
made it hard to do (you had to enable 'expert mode') otherwise
people would accidentally try sharing ext2/3 file systems and end
up trashing them.
