If you mean NICs, then yes.  Multiple people have used this

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
