Multiple OSes, 1 Mozilla profile?

I have a triple boot computer, Win98, Win2k and Red Hat Linux 9. I want Mozilla mail to use the same profile, or at least mail folders, among them all. The goal is to have the mail all in the same place no matter which OS I am running. Each of the OSes have a different default path to the profile and mail folders.

Can I do this? Any pointers?
