If you pull out the network, then you also lose the server-- the same net effect as pulling a diskette out of the drive when you are running a program off of it (well not EXACTLY-- with a disk you can always cleanly re-insert it and the mac will recover) If MultiLauncher is designed for running software off an AFPServer, you don't need to worry about the case where the user unplugs the network. Actually, it's pretty easy to check if the user has disconnected the network-- periodically look for the server-- if you cant find it, you have to panic, right??? There are a few other more important problems like "what if the server is down before you run anything?" "what happens if the net 'hiccups' for a few seconds", "what if your machine crashes", etc. etc. etc. I guess if you are running software off a server, you're screwed if the net goes down anyway... Also, if i'm not mistaken, MultiLauncher works via ATP, not ASP-- using ASP would make life a little easier for a programmer by handling timeouts, etc. -dave falkenburg disclaimer: this is ME talking, not Apple
