Interesting Dan!!!.

Iv'e read with interest the posts on ethernet collisions and
their adverse effect on network performance.

Problems of that nature should be addressed during the initial design of the network and again for modifications.

Some of my observations on network usage are as follows.

Many stand-a-lone pc's connected to a backbone hardly send much
onto the networki (that why there stand-a-lone). Other are conected
to say a novell network connected to the backbone. The client/servers
conduct most business among themselves again little in the way of
packet transfers onto the greater lan that they are a sub part of.
Hence little collision problems . In most cases capacity problems would show up in servers and mainframe cpu's before the ethernet bogs down. Matching those elements is a large part of network design and resulting performance.

Moreover, as far as communicating to the wan goes this is not
usually something that is done by nodes as a matter of routine.

The network design attempts to limit all nodes sending packets to
all nodes all the time problem. The network does not see all work done by the pc's. the wan does not have to see all work done by the lan(s)
The plant does not have to see all work done by corporate.

Lastly, alot of the transfer of data involves other equipment.
Namely, modems, T1's and other muxes.

No doubt some might have trouble. Some might not be able to live with 10base t. However, I think that the aceptance and adoption of ethernet has been the ability to design networks that suffer
minimal collision problems for most users.
