Plugins, No. I don't use any now, and don't think the trouble of 
multiple installations would be that big a headache for me.

Having one archive for emails, across multiple (3 for now) computers? Yes.

Being able to check/download POP3 mail from any of the machines and have 
it go into one archive? Yes!

Having more than one machine in use with Thunderbird open and active. 
Yes! Just not in the same email message. I'm thinking this should be 
something like record locking on a database.

If Thunderbird can't do this, is there another email client that can?
