[j-nsp] Junos OS Evolved

[Alain Hebert]

     I haven't unpackaged an Evolved distribution yet, but my experience 
with WindRiver licensing back in early 2000, it would be pricey.

     As for FreeBSD, they could have gone the way of upgrading the 
kernel (I saw some evidences about 10.x but no confirmation yet) but 
depending of their initial work done during the 4.x days, switching 
might have been a better financial choice.

     Device support wouldn't be an issue pretty much all the worthy 
stuff works on both...  and with virtualization its not an really issue 
anymore.
