Do you object to the idea of having qemu call to a helper program 
directly or to the idea of having the helper program in qemu at all?  
Splitting the helper into a separate project may be a more constructive 
discussion as was suggested by Arnd.

As a separate project, libvirt could also make use of it and use -net 
tap,fd= if it wanted to do crazy things.  From a distro perspective, 
it's just a matter of setting up dependencies to make it Just Work so I 
don't object to it that much.  It's just a bit annoying to create an 
entire new project for a few hundred line helper.
