Best way to share Thunderbird Profiles across multiple machines.

[Young]

In the past I've shared Thunderbird Profiles between Ubuntu and XP on a 
dual boot machine.

Now I'd like to share Thunderbird Profiles across a local network 
between 2 Ubuntu machines and 1 XP box.

Instead of a Network Area Server, I want to designate one machine as the 
first one on, and have it host the Thunderbird Profiles as well as other 
files across the local net.

By Thunderbird Profiles, I mean the complete set, multiple email 
accounts, and their associated mail folders.

What's the best way to make this work? Anyone here have this working 
already?
