Absolutely.  I wanted to not have a hard dependency on PolicyKit to 
start out with but that's always been the plan.  I'd like to eventually 
add an optional PolicyKit dependency and when that's available not even 
bother with the qemu acl file.  The nice thing about PolicyKit is the 
desktop integration.  It's a much better user experience to allow a user 
to be prompted to allow qemu to access a bridge vs. having to error out 
to the user and tell them to muck with a config file.
