If it is so that you have only one user interface client:
Wouldn't it be a solution to put the server close to your clients office?
Then it is only necessary to have open lines from his office to the nodes.
If one of the nodes
is unavailable then the fun is over anyway wether you use sockets or not.
The same goes for the boot location, your customers office is the only node
(??)  that needs
communication to the other for the other purposes too.
If your lines keeps dropping, you might catch some exceptions in the
application to retry later.



About my question of the versions. I have a couple of problems with GLADE,
and it would be interesting if
someone with a 3-14 or higher could have tested a little program for me :-)
