Even plain old asynchronous SCSI should be faster than 10Base-T, but 
I don't have any more insight than that.

More likely it's that nobody can make money on SCSI Ethernet adapters 
any more.  They're more expensive to design and manufacture than PCI 
or CardBus Ethernet cards (custom design vs. standard parts), and 
since there aren't crowds of people spending money upgrading 
non-PCI/CardBus computers any more, it would be pretty hard to make 
any money off them.

Also, since we're now getting to the point where used PCI Macs are 
quite cheap, anybody making an upgrade for older computers has to 
consider that if the price is too high customers are going to upgrade 
the whole machine instead.  Many years ago I knew some people who 
were looking for a NuBus video card so their IIsi could drive a 21" 
monitor; they ended up just buying a whole Quadra 605 because its 
built-in video could do the job, it was a much faster computer, and 
it didn't cost much more than a NuBus video card did.

USB can't.  USB is only 12 Mbps, and if the phase of the moon is 
right you might be able to actually get 7-8 Mbps of actual throughput 
on it.

There are USB Ethernet adapters, but they're only marketed for PCs. 
There's not much incentive for the people making them to do Mac 
drivers, since every Mac with a USB port built in also has a 
100Base-T port built in.

FireWire could keep up, but I'm not aware of any FW Ethernet adapters.
