OK, I'll be reviewing & improving the page.

What do you mean by IP-port?

The Internet has sockets.  
  http://en.wikipedia.org/wiki/Internet_socket
In the most common terminology,
  socket = ((IP address),(port number)).
Each protocol has a distinct port number as explained in 
the Wikipedia.  For example, a destination socket for SMTP 
might be ((10.4.0.1),(25)).
  
A network adapter is configured in software as a network 
interface.

Are we discussing one machine or two machines?  Is ETHO 
running on a Linux machine which also runs an MTA?  Are 
ETHO and the MTA on separate machines?  In the second case, 
does "the MTA" belong to you?  Is it on your premises?

Why?  Ethernet is fast and supported by *nix and by ETHO.
