Well after a little more digging around I found that pigpio from joan is actually already able to do all the things I wanted.
What's even nicer is that it has a nice python wrapper
I'm going to migrate my project over to pigpio, and see how that goes.
If anyone wants it, here's some basic test code I used for servoblaster, within python -
call(["sudo ~/PiBits/ServoBlaster/user/servod --p1pins 11,19,16,18"],shell=True)
call(["echo " + str(self.panPin) + "=" + str(self.panPos)+ "% > /dev/servoblaster"],shell=True)
where panPin was the mapped pin number (servo 1-4 etc)
where panPos was the position in percentage of the servo (e.g. 50% is centered).
Really glad to see there's multiple people making great tools to build with! Maybe one day these projects can merge into an "official" branch everyone loves (yeah you can tell i'm coming from the Arduino world..!)
