More than enough for LCNC, deloptes.  Its running on the pi with only a 
gig of ram. In a weeks uptime, it has not touched a 10Gb swap. Hasn't 
been particularly busy but LCNC has been running, with the machine power 
disabled all this time. I have that one rigged to shut off all machine 
power when motion is disabled.
