NYCAnalyst - in the most part, yes. Sales or market making - in the vast majority of cases that is what anyone on a bank trading floor does. Moving to a prop role involves showing that you can deal well with that - in certain ways it is more difficult (getting positions you would never want due to a client), in certain ways easier (less emotional attachment to a bad trade). Much prop trading is likely off the side of the desk, but even then is within what the desk could use as hedging products (index trades through signal models perhaps). Cutting down on that in many cases wouldn't make a large net difference, as I have seen more of those go bad than good.
Holding a proprietary position as hedging will always going to be fine - it will become a nightmare to follow, but ultimately it would be very similar to hedge accounting for IAS39 (FAS 133) which banks have had plenty time to get used to.
I really can't see why Bernanke shouldn't get a second term, and the seperation of monetary policy control within the Fed away from government interference is critical - getting back on monetary policy is a bad idea. The need for better regulation is obvious - not necessarily increased regulation, but almost certainly improved legislation as Wall Street has driven buses through the loose netting that Washington has in place.
