In the previous thread this was discussed in  (See "Patch: Mobile 
dongles") the proposal was that inhibit would be triggered by the 
presence of module 'usb_wwan'.  Jerry submitted patches that did that. 
Paul was wondering if there was a better way than looking for a module 

Powerd already has a mechanism where it disables suspend while an 
association is in process and Paul was wondering if you could leverage 
the existing infrastructure for this.

The thread dies after that.  So I think anyone wanting this to get 
integrated as a stock feature should investigate if you can use a NM 
hook to send the DBUS message to powerd to inhibit.
