Yeah but given all these fancy firmware restrictions (not to mention 
that "network booting" inherently means two machines), one can get 
really creative.

Like... how do you boot an ISO file? (E.g. Solaris DVD rescue prompt.) 
A: Assuming there's already an installation, you store the ISO on disk, 
make sure it's in one extent, and then hack the partition table to point 
to it. Then it's a matter of "boot disk:e.."
