Rude!? It's rude NOT to! :-)

I wonder about the cloth... small pores plug up ASAP with fats and oils, the main problem with kitchen waste. Your idea for settling is good, but it really needs to be still to settle; as you add water is stirs the mess and un-does the settling.
Make sure you have enough capacity on the INLET side of your filtration system... my crude system uses a huge funnel with about 1 gal capacity. It can take many minutes for water to filter through. Our filter was simply cheesecloth and mesh fabric paint filters with elastic edges, both from the hardware store. It plugs up daily or more and we have to empty the filter into a trashbag,

I suspect your soaker hose will plug up (playa dust concretizing on the outside, oily goo on the inside) but it could work out great! In fact, water might not even make it to the other end, through evaporation!

YEah, it's only tiny fraction of a PSI, and with soaker hose plugging even slightly, flow could stop altogether.
However gravity is "free" (yeah but you gotta lift the water up to use it)...!

Yeah, but I'm filled with opinions, worth what you paid for them... test, test, test! Test with real dirty water, and bring a backup system! Everything goes wrong on the playa...! :-)
