Sounds like you just described "MoneyBall" :) Seriously, though - thanks for the insight. Hadn't thought of comparing to a hedge fund, and after reading your description, it seems obvious. To add some color to an ETF analogy, an ETF in the financial markets is basically just following an index, which is often created by a firm like S&P (and there are over a thousand of those indices). So, one index may just be "buy all the companies that have dividends", or "buy all companies that have a price to earnings ratio greater than average", or "buy all companies listed on the US stock market". I guess in poker it could be "call on everything", or "fold unless you have at least a three-of-a-kind". Basically, it would be mechanical. Of course, you can have reasonably complex ETF algorithms that have multi-pass filters (such as P/E ratios, Debt/Equity ratios, Dividend minimums, etc.) all in some combination. So maybe there could be something complicated like "bet 1% of your holdings whenever you had a pair, and bet 2% if at least one player folds." This is just a made-up example, but the rules could probably get intricate based on the math and different situations.
