Any machine that isn't completely disposable. For most users this includes 
their local workstation.

This actually argues against using kqemu as it only works in on "native" 
hosts.

You've been lucky then. I bet the only reason you haven't seen any problems is 
because kqemu is too obscure for anyone to bother attacking it.

Neither can kqemu. Installing an unsupported third party kernel module is 
about the worst thing you can do from a security and stability standpoint. I'd 
expect any respectably sysadmin to laugh and kick you out if you requested 
they do this on any of their shared machines.
