Hmm... I thought everything still had collision detection and would work on a bus, like what you'd get using a hub.

There is normally no collision detection beyond 10Mbps. Also PoE would not trivially work daisy chained.

100base-Tx is specified for shared media (hub rather than switch), but I think you need some electronics to make a hub, you can't just do a passive connection, and so you probably end up with a hub IC and may as well use a switch IC instead.

It might work in so far as you'll get packets through. The performance would be abysmal, though. Modern Ethernet is built around switching.

Would it really be that bad? If the devices were well behaved (ie. not too noisy, no gratuitous ARP etc) and the application could assume that most of the time either zero or no devices will be communicating, would it be that bad?

This is something I might test myself. I have a couple of audio devices that will never be both "active" at the same time. In my current layout I need to run either two cables or just another switch and it just seems a waste. I wonder if I can buy daisy chained cable so I don't have to make one...
