There are two options here:

1. Different platforms accessing the same database
2. same platform (different machines) accessing the same database.

1. Easy. When you do a configure set the prefix (prefixes) approrpriately so
that the executables go to an appropriate place and the databases point to a
shared (NFS or similar) drive containing the config files. Obviously you
have to use the same mountpoint on all your machines for this to work (I use
/site/share/EMBOSS for the config and /site/databases as a root for the
databases. In this case /site/bin is local, not shared and contains the
appropriate binaries [or can be a symlink to /site/Linux/bin,
/site/IRIX/bin, /site/Solaris/bin, /site/Darwin/bin as appropriate if you
are supporting more than on emachine on a particular platform]  )

2. Can be done in the same way using a shared drive for the executables. One
gotcha is that EMBOSS, despite all efforts, does not compile statically so
you have to ensure that the library versions are the same across the various
platforms or you will get runtime errors.

Either of these methods will reduce the maintenance load considerably.

In my case I use NFS for the data directories and use a nightly scheduled
rsync to synchronise the executables and config files with the master
machine as these don't take much space and it reduces the network overhead.

Hope this helps.
