So the GNOME hook for inhibiting suspend seems to be in gnome-session 
[1][2]. For 0.92 we can look into possibilities on using that. As we 
already include parts of the gnome session manager code to handle 
shutdown etc we might be able to switch to the gnome session manager 

For 0.84 we can do what powerd offers, creating a file based on the pid 
in /var/run/powerd-inhibit-suspend/ (those are removed by powerd when it 
goes into suspend the next time). I modified James's example to handle 
the share and join case (in the base activity class). Quite good results 
here in terms of usability.

I guess one wants to inhibit as well when one invite someone to an 
activity. Not sure we need to inhibit suspend when we display the 
neighborhood view. The presence (buddies and activities) should be 
synced when we come out of suspend (Upower+Aavahi [3]). Not sure we need 
as well to inhibit here then.
