May I suggest something to all of the potential ASL hackers here?
I have to run windows on my desktop, but I run vmware on it as well. I have two ASL 2.0 installations inside their own virtual machine - working flawlessly (trying to set up VPN between them [;)])
Anyway. What I'll do now, is to install the ASL hack kit on one of them, do the compilation there, and move the module or the binary code to the real ASL firewall.
VMware can also be run on linux if you prefer to do so, but it is incredible value, as you don't have to have a second development system.
