Hi louiscox,
I have recently managed to setup an appleshare server between 10.9 and 7.6. It uses a linux machine as a bridge but I use virtualbox for that so I have only 2 computers in this network.
I made a post here explaining everything I have done to make it work => https://68kmla.org/forums/index.php?/topic/23381-appleshare-between-classic-and-mavericks-another-way/
This network solution is one way only. I can access my 10.9 folders from 7.6 but not the contrary. I use this setup almost everyday (I directly work on my 10.9 files from 7.6) and still had no problem.
