I was envisioning multiple clients connecting to one database. I could have one daemon/database running here and have any of the machines run clients that connected to that one instance. The daemon would normally be running on the machine that had TNC's. In an EOC setup, one machine would be hooked to the TNC's and to the internal network (and perhaps an outside network). Other machines on the local LAN could run clients that connect to that one daemon. Any machine might have multiple map clients and/or multiple messaging clients up at the same time as well. > It seems the daemon idea is poised to be a typical unix daemon, > forking a copy of itself to service each new connection.

Yes, and if the daemon/persistence layer were very cross-platform and maintained/tested that way, the clients wouldn't necessarily have to be. > Since the databases are frequently designed to allow network > connectivity, would the daemon hit multiple databases, possibly > networked? Give me a reason. It would complicate the code. Would there be any benefit? > Of course when we start talking about network access the big issue of > security rears its ugly head... Yep. I think Gerry already suggested SSH/SSL connections. We could perhaps require that for network connections from a client, but not require it for local access. -- Curt, WE7U. archer at eskimo dot com http://www.eskimo.com/~archer Lotto: A tax on people who are bad at math. - unknown Windows: Microsoft's tax on computer illiterates. - WE7U.
