Argh!  Using a sledge hammer to drive a 6 penny nail....

Sure, you *can* do that.  However, since the docs on pppd indicate that 
it will invoke the script /etc/ppp/ip-up when a connection has been 
established, and furthermore, the /etc/ppp/ip-up script [at least, as 
distributed by Fedora] looks for [and then invokes] 
/etc/ppp/ip-up.local, you could do exactly what you suggested with the 
following:

#!/bin/sh
mozilla &

This uses the systems built-in notification mechanism, rather than 
writing custom scripts which may or may not take into account various 
failure options.  As far as "killing" your wvidal process, how about 
"ifdown ppp0" instead?  Alternatively, you could use the "modem lights" 
applet to your panel, and connect or disconnect from a GUI.

While interesting, this would kind-of defeat the purpose of using 
wvdial, wouldn't it?  It also doesn't seem to be very effective in 
dynamic situations [such as typical dial-up, where you obtain a 
different IP every time you connect], but I could be wrong....
