You won= =FFt get that with a C2K system at 25W TDP, (4 x GigE that can run at 2.5= Gbps per port, and 2 SATA 3.0 ports currently) but Intel owns IP for both= , so if that becomes a differentiator for design wins, I=FFd expect a fut= ure variant to cover. >=20 > But by all means, port FreeBSD to it.

IMO the thing that prevents ARM from becoming tier 1 is manpower. -- Ian
