Sharing online banking information among computers

[Paul Abrahams]

I run Gnucash on several computers, and I would like to avoid having to 
configure online banking separately for each one.  How can I do that?  In my 
case the computers are all running Linux, but I'm also interested in how to do 
it in Windows or, even more challenging, how to do it between a Windows 
Gnucash installation and a Linux Gnucash installation.
