I saw that you put online all of the root packages corresponding to the official sources listing of the Darwin 9.2-9.1-9.0 releases,
and I was wondering if unpacking the needed base packages I would be able to create a bootable version of Darwin to be run on a 

generic PC [not a mac] without breaking the APSL license agreement.
The target is to have a small firewall/vpn/mailserver solution based upon Darwin 9.x.

Thank you all
