Re: [Xen-devel] plan 9 status

[Wesley Parish <wes.parish@xxxxxxxxxxxxxxx>]

I would've thought a (legally) efficient way of doing that would be to have a 
library-set available under the LGPL, that call the GPL code and are called 
by the non-GPLed guest OSes.

I'm not sure about the actual efficiency in terms of processor cycles, of such 
an approach, but if it collocates the lawyers in the dogbox, which is where 
they should be, instead of breathing down your neck, that should be an 
acceptable trade.

Just my $0.02 (and it's very highly inflated of course!)
