So you don't actually need to be ethernet 10baseT compatible but you
would like similar speed and distance, would like it to work over twisted
pair, and want the clock and data combined in one signal?

You don't have to support multiple nodes - just between two
PICs.

OK, well....I have no idea!  Glad to be of help - and Merry Christmas! ;)

But if you don't mind relaxing it a bit you could use you're UART or
SSP, with RS-232/422/485 drivers.  That would get you 5Mbit pretty
easily (using SSP), and you would actually be able to see your family
too. :)
