I didn't think of that.  PPTP would still need to be modified because it 
installs a single route to the remote server replacing any existing 
route.  That code could be removed and performed by the invoking 
process, which might be Network Manager, or could be a simple wrapper.  
I don't want to propose removing existing PPTP function (updates to 
routing table), merely an incremental change.

I agree that other protocols could benefit from this, but Network 
Manager looks rather harder to change, particularly as I'd also have to 
change those other protocols (e.g. changes required to pptp.)  It seems 
productive to demonstrate utility by changing PPTP, and leaving a 
generalised solution until we have actual (rather than theoretical) need.
