That's certainly doable.

The ping option would be better, as it would be independent of any of 
the various networking setups that are likely to be found in the field. 
So it would work with ppp, isdn, etc.

What about distributing an rpm package that additionally includes 
xs-specific scripts for wwwoffle, apache proxy configuration, and 
/etc/init.d ? That way there's no need to do sed re-configuration back
