I mailed a posting a few days ago about a problem I was having with Revolution when launching a unix command-line application with the shell() command. The problem I'm having is that the first time this particular unix call is invoked, it requires the Mac OS X authentification popup to display, which causes Revolution to hang for some reason.
A gnarly problem you've got here. If your installer software can launch PPPSetup then I would just go with that.
I don't think it's the authentication itself that is causing Rev to hang. There are other problems here. (Even after authentication is done, the PPPSetup command hangs for me.)
PPPSetup launches a second instance of itself [1] as a subprocess- which apparently confuses Rev and it thinks that it has to wait for all processes to complete. (or maybe something weird with TTYs or signals)?
In Terminal, PPPSetup returns immediately, or waits for authentication, depending whether authentication has been done. Just an observation about it's varying behavior in behavior in normal conditions.
In Rev shell, PPPSetup always hangs no matter whether authentication has been done.
In applescript with the "do shell script ..." version of this command ALSO hangs no matter whether authentication has been done.
In Terminal I can background PPPSetup with job control & no problems.
In Rev shell I cannot background PPPSetup with job control & (even by writing a separate /bin/sh script to do it).
In applescript I cannot background PPPSetup with job control &
[1] I think PPPSetup is spawning other processes because I keep ending up with these long running processes "./PPPSetup" when the process I started was named "./PPPSetup m username password 7035551212" and had already ended.
# ps ax | grep PPP 535 ?? S 0:00.07 ./PPPSetup
