application to be running in order that the embedded server start (hence a
dll).
Now what you are asking for would still need a host application to be
started (or running) for these other PCs to start using the embedded server
(in classic mode). Once the host application exited, the other PCs would
loose their connection.
If you want persistent connections then you are really wanting SS of CS to
be running independently on a PC (server), so that any other PC can connect.
And that solution is already available.
Cant see any other way.. unless you want to host an application which starts
the embedded, if you create this, it's called a 3rd tier and you can let as
many connections as like pass thru this using the embedded right now.
