I can't say for certain how much current this would draw, it's not 
going to be out of the ordinary by any mans and will only require 
a +/-12 supply.  

If anything ever requires a smaller supply voltage (Milton for 
instance uses +5), I'll handle that by including on-board  
regulators in the module itself.
