A couple of things we've learned - the PCM monitors the current draw to the compressor and protects against blowing the fuse. Beta testing will tell us just how smart it is, but so far I haven't heard about any of the fuses blowing.
We don't know that extra PCM and VRMs will be allowed under the rules, however the vendor suggested that additional ones could be powered from the 20/30 amp breakouts on the PDP.
In addition, (and this may have been just me), I had assumed that the VRM connections were individually rated at the amperages listed. However, the connections at each voltage / amperage rating share a rail. For instance, the 12V 2A connections are 12V, for a total of 2 amps. Not 12V 2A each.
Also, I strongly recommend visiting Mark's team webpage (358). The testing they've been doing is really above and beyond:
