If the parts are decided then the final choice is merely how many and
how much
as you state here

Yes please :)
I have five WizNet WS5300 and five CP8900A here. I don't have any CS2200.
Having another 20 or so is about $120 of reduced cost just for the chips
alone, which is very attractive since I am trying to do this project as
affordably as possible for buyers without making a profit myself.
I'll mail you off-list.

Dave, I think I have up to 25 Wiznet chips and unpopulated PCB's (SPI
interface) unused from an abandoned project. You can have them if it helps.
The PCB like all my designs was created using the QL PCBDesign software so
it can easily be altered to the QL bus.

Please add the CP2200 to the list of devices under consideration.
I did just look it up and it is comparable in features to the CS8900A.
With
a brief search, I might be able to buy CS2200-based ethernet cards and
harvest all the components needed off them quite economically, for
example.
I am a little disheartened that ethernet on the Qx0 is not used by any
QDOSMSQ* versions.

original QL owners are going to do with this thing anyway.
- Only 4 parallel connections. That's 4 more than QLs usually have,
but still not exactly many.
- IPv4 only with no way to upgrade if it is ever deemed necessary.
All in all I'd say a real Ethernet chip would be much more
future-proof... if you can get the software for it working.
Of course the W5300 is also a proper ethernet chip as well, linux has
a driver for it not using the internal stack!
