multiple installs > one database

[John Snippe]

I am needing to be able to access email and other files from various  
locations, and have set up a Dropbox account to facilitate that (1: <http://www.dropbox.com 
> )... it maintains sync of files placed in it's folder between  
various locations using the same account via internet.  Totally  
transparent and very nice.

So my question is two-fold:  it is possible to have 3 or more installs  
of Powermail be able to access a single database folder, and/or is it  
possible for more than one user to access a database folder at a time,  
or more specifically, is the database capable of autosave from  
multiple locations at the same time without corrupting?   I ask this  
'corruption' question because I already know, and it has been  
documented, that there is an issue in this regard using Dropbox with  
Filemaker, and we've had to take measures to ensure safety in that  
regard.

Also:  is it possible to have separate databases on a single install  
for different email accounts?

Does this even make sense to you?  It does to me, but I fear my  
explanation may be somewhat lacking...
