Actionscript to mount network share

[Mark2000]

Hello. I'd like to create an actionscript app that will check to see if an airdrive is mounted and, if not mount it and then launch itunes. The reason being is that I have my itunes library on the drive and I'd like to not have to remember to mount it every time. Mounting it on startup works, but often I move off the network and back without restarting. I could probably figure this out myself, but I really wanted to have an if/then statement that doesn't try to mount the drive if it's online already. Thanks for any help!
