Trub,
A peristaltic pump will work fine, but you should T a vacuum gauge into the line. While I am not personally concerned about impolding a carboy if it is full of wine (which exerts a fair outward pressure on the surface of the glass), others are iffy about it, and I have no first hand experience. My feeling is that light bulbs hold almost complete vacuum, and the glass is paper thin. I feel that any carboy that implodes under full vacuum was already cracked.
Another great use for a peristaltic pump is that it is ideal for racking and filtration. The wine never touches any part of the pump except the food grade tubing, which can pump a gallon of SO2 solution first from one bottle to another first. Since the flow rate is low, you can put a racking tube just above the sediment after fining and draw off the wine. Even if you do lose prime, the pump is self-priming up to almost 30', so it's easy to restart.
As far as I am concerned, peristaltic is the way to go. Got a spare you can send me?
