One thing I don't know is whether the A/B/G cards can run A simultaneously
with B/G.  My guess is that the answer is no, since it's *very* difficult
to design something that can send and receive at the same time through the
same antenna, even in different frequency bands, and sharing the
transmit/receive scheduling between the two would get messy, if it's even
possible.

I presume the "512 or 768 pipes" you're talking about is for the WAN.  I
can't imagine anyone wanting a LAN that slow.  It's not even that fast for
a WAN; I have 6M/600k DSL at my *house*. :-)

Anytime you start doing something ike file sharing, it's almost impossible
to have too much bandwidth.  Or using VNC, though that's mostly VNC's
fault. :-) VNC is annoyingly slow over Gb Ethernet.

Well, I did say "same equipment". :-)

I wasn't referring to independent networks, but to the "upward
compatibility" feature of G with B.  This is in the same sense that 66MHz
PCI is "upward compatible" with 33MHz PCI, i.e. plug in a single 33MHz
card and everything switches to 33MHz.  Similarly, *on the same network*,
the presence of a B station drops everything to B speeds.

Hey, don't knock HyperThreading.  Recently a case came up where Linux
needed HT just to be able to output text to the console at a reasonable
speed. :-)
