If you mean NICs, then yes.  Multiple people have used this
configuration
in products.  They just must be ducking. :)

I don't know the answer to this.  More helpful would be a specific list
of things you are intested in.  Do you mean PPP, SLIP, etc?

Eric Valette has reported results of running 100baseT.  I recall it 
was on the order of 85-90% of the theoretical limit of the media.
There was no tuning and this is with the TTCP benchmark.

People (including Eric Norum) have regularly reported 10baseT
TTCP results at the theoretical limit of the media on his modest
68360.
