Try inserting a "trick" birthday candle into the center of the egg-crate filled with stuff and then pouring the candle wax over it all. The birthday candle will light and not go out and it will very easily start up the egg crate. If you have some fluff (cattail, milkweed, pocket lint, cotton ball you can stick just enough to catch the spark on the tip of the trick candle and this will light easily from a spark. The full combination provides tinder and kindling since the wax / sawdust / egg-carton flame bomb will burn long enough and hot enough to start wrist diameter fuel even if it is wet.

This is certainly a bulky / heavy item to carry about but there are circumstances when it may prove invaluable. I usually will have one or two in the pack for a long trek. Always have one in the BOB and car kits. Wouldn't consider it an improvement over the cotton / vaseline in a straw for the PSK usage.
