Here's an idea i've been toying with:

I'd like to use the mail storage on my home machine (Apple's mail client mbox's) via an X client. I'd like to ssh -X and then fire up an X client for reading/sending mail while I'm away from my home machine.
The advantage is that, I have all my mail (both read and sent) stored on my home machine. so sent mail messages that are otherwise lost on whatever machine I happen to be using at the time, are not an issue. likewise, I have a secure connection to my home machine through which "my" mail is accessible/usable.

While I'm home, I can use the excellent Apple Mail.app, and on the road I could continue to use my personal mail folders stored on my home machine.

Has anyone given this any thought/done it/seen information to this end?
