I like the idea of maybe trying the nitrogen in the forks. I have a "generator" at work. Maybe I'll put 1-3 PSI of the stuff in my forks for the April ride and see how it works. It wont reallly increase in pressure with heat like comp. air will.... Maybe it could work? maybe nitrogen for ur tires but not really needed for the forks... when a gas is compressed it heats up and when it expands(un-compresses hahahaaa...is that a word?)it cools so the net temperature effect in the forks is zero except for friction...the only exception is hydrogen gas which is the opposite(cools when compressed & heats when it expands). the rear shocks being a sealed system uses nitrogen to increase the longevity of the oil...no oxidation or moisture with dry nitrogen gas. the forks have a very small volume to hold the pressure so setting the pressure is difficult...just by checking the pressure u drop the pressure 1-2 psi...that's why i overfill and bleed it down to the desired pressure. in the XRL forks ~5 psi makes a significant difference with everything else left stock and compression set near the factory reccomended setting...reduces fork dive with the trade-off being a little added harshness as i posted previously.
