I have to say, file sharing in OSX and above just stinks on ice. With all of the drawbacks of the older system, simple file sharing was one thing that was great.
With X, you need to create a whole account on each computer (and even then you won't be able to see each other's files, just the files you each own), or you need to store EVERY COTTON-PICKIN' FILE YOU'LL EVER NEED in the "Public" folder.
This "feature" is among the stupidest "improvements" I've seen this side of the Windoze world. We may get stability and memory management from Linux, but this particular issue drives me insane. It's annoying enough that I've kept my central Mac at 9.2.2, and I just push everything onto it from the OSX machines and then pluck it off there from the other remote machine.
Unless I'm just incredibly stupid and I'm missing something totally obvious, which is always a possibility...
[edit] D'oh! A definite possibility, since I just posted this in the wrong thread! [/edit]
