Yes, and you're supposed to buy them. Except if the second bit is 1,
because then it is a logically assigned Mac-address that is temporarily
valid (and every device (or the FBI for that matter) ;) should be aware
that this address can not be used to identify hardware).

All Internet traffic is liken to a finger print.
The trace route is unique.
If two machines were to be on the same ISP, they will never have the identical trace route, prove me wrong if you can :-X .
The FBI uses all traffic information, including the traffic information from Internet routers to track evil packets and people, of all kinds.
No one is safe from this type of monitoring, not even YOU =-O .
Follow the rules of the U.S.A. and do not break any laws, and you will be left along to prosper as you may, other wise they will be watching you very closely.
Just leave the MAC addresses alone, they have a purpose and a need to be what they are.
If you are worried about Intranet/Internet security, do the Crypto, not the MAC'o, the Crypto has 64 Quadrillion encryption codes available, much more than MAC or IP.
ZWorld/Rabbit Semi sells an encryption module which is royalty free and very cost effective, and on top of that easy to implement.
My 2 cents worth! With a penny change! :-)

Put two machines behind a masquerading router, and they will have the
same traceroute (since they will both appear to "be" the router). You
cannot see the MAC address outside of your LAN because it will no longer
have any meaning once it leaves your LAN. MAC addresses are part of
ethernet addressing, not IP addressing.

Technically that would be possible, but if you see how difficult they
still find it to track down people that blatantly post pictures of their
own rape victims, exposing their IP addresses, you'll notice that we're
far away from your slightly paranoid view. ;o)

What you do with MAC addresses only affects your local net and has
absolutely nothing to do with the outside world (unless you connect
directly to some big backbone through ethernet) and "the FBI" will not
see it. You're not even breaking any laws. You're just breaking your
network if you happen to have a duplicate Mac address. Besides, as I
said, MAC addressing allows for dynamic temporary addresses, with the
second bit set to 1.
This changes with IPv6 of course.. ;o)

No offense or flame intended but I think this topic is dead, let’s quit with the pissing match and the Government spying crap.
