IMHO beating VWAP is a valid strategy per se. if you can beat VWAP you can offer to institutional clients a VWAP minus price, which spells ... real business.
my (theoretical) understanding is that consistently beating VWAP has less to do with usual day trading strategies but with very intensive modelling on lowest possible level of data. i think it is simply the ultimate scalping strategy. searching for streaks in ordersizes and this kind of thing. detecting the trace of someone big entering the market.
BTW the discussion probably depends as well on what time horizon of VWAP we are talking here ...
excuse my naivity, but is it really the case that big houses let human beings run the VWAP books?

, hope none of them is around ... ), so it might be worth a consideration to become an intermediate of some wholesale VWAP shop and skip something of ... well, maybe not so good an idea, since you cut your own job ...
