With all due respect, I was an " old-fart" in my youth. I use
to love sitting around campfires with old hunter (gathers?)
and shoot the shi____ about life.

Beside my tantrums are so ledgendary, they often lead to 
a circle of folks joining in and chanting childish limricks
to a rythymic dance.   The Tequila goddess usually follows
up my antics with show stopper (hoot_nanny) you cannot 
believe.........

preening code and riding a harley are differnt things? Boy, I did
not get that memo.

Virtualization is easy to shoot down for management types. Just start
them on a task force adressing all of the security issues opened up
related to virtualization.... [1]

Well, 10 G Ethernet is coming to systems near you, sooner than later.
100 GE  is availabe for routers now, if you have loads of CASH....
Once again, Juniper is killing the competition, imho.


Beside, virtualization is about to take on new meaning. [2] Imagine
a state machine for handling low-level register-memory tasks, whilst a
concurrent, real-time linux kernel handles traditional routing engine tasks,
both running on the same "bare metal" in a new twist of
virtualization.......  Very secure to boot, unless the NSA influences
the foundry's methologies for laying out the "bare metal"......


On the memory side of things, there are many viable options that the
different ARM [3] vendors can choose from for such challenges. 

Personally, the memory type that accompany the GPU, I think will change the
game for such needs, when the GPU become fully integrated with the cpu
cores (like what happend to FPU) in various SOC offerings. Granted, Arm is
late to the communications embedded systems efforts, but many of the top
hardware designers in routing and networking, are working on 
ARM implementations for comm gear, as we speak. 

ARM is simply whipping the dog_snot out of the other architectures.......
