There's no good way to do it with ifconfig, but one way that will work
(and we've used similar methods in other apps) is to create an array or
hash of all known wireless interfaces.  Basically:

an
iwi
ipw
ndis
ath
wi
ral
ural

Then, you can use ifconfig -l to list all available interfaces, and do
further processing on any that match your static list.

You need to cleanup after your process.  In Java, this is done using the
Process.waitFor() method.  I'm sure there is something similar in C#.

I'm not so sure.  Why would you want it to delete SSIDs just because the
interface goes down?  If it were brought up, having the SSID configured
would give it a better chance of reconnecting.

I haven't yet given myself over to Mono, but the screen shots look
promising.  You might want to expand to WPA support as well.
