Anyone trading/investing in liquid natural gas? Which companies are the leaders to follow in this field?

Well... Sorta thinking that liquid natural gas (LNG) might be a market yet to be discovered. Of course, all of the large companies are going to be involved, but that gets buggered up because of relatively decreased volatility compared to smaller companies. Of the listed natural gas players, I don't know who is LNG progressive and who is resting on their laurels. Anyway, I though surely someone is already on top of that... maybe I won't have to dig through all of the company reports. The AMEX Natural Gas Index (Reuter's us!XNG) is listing 15 companies right now: \\\\BF\\US;BR \\\\BF\\US;DVN \\\\BF\\US;EOG \\\\BF\\US;EP \\\\BF\\US;GAS \\\\BF\\US;KMI \\\\BF\\US;NBL \\\\BF\\US;NFG \\\\BF\\US;NI \\\\BF\\US;PPP \\\\BF\\US;STR \\\\BF\\US;WMB \\\\BF\\US;XTO 6 month price ROC ranges from 5-50%, the average is about 21%. That's great. I think it's only gonna get hotter!
