Why are you opposed to stocks/bonds? Not implying the trend will continue, but there are commodities and diversified foreign stock market ETFs that returned 50-100%+ last year with greater liquidity and less risk than nearly all startups. Also, there are bond ETFs/funds that are very liquid. I am a big fan of the JNK ETF (~11% interest).
