Great... Then there only need to be some place where kernel and rootfs 
can be downloaded in binary form... Packages is even better but binary 
files is a huge improvement.

Setting up a complete build env to just check it out is a big hurdle. 
And as script/mono/java packages aper/mature it's not needed even for

Think this is what I wished for in poor wording (pardon my English). The 
problem I can see is that qemu use dhcp for the virtual clients and 
openmoko aper to us a hardcoded IP#... But I will check this out (I'm on 
a 32 bit host).

Thanks for the pointer!
