What kind of lime do you recommend? Ag lime or quicklime? I think both might work; Quicklime, or burnt lime (Calcium hydroxide) would certainly hasten the decomp, (Dad used to put it down our old privy) but it is very chemically reactive and not something you would want to get on your skin. Ag lime, of course, is just crushed limestone (Calcium Carbonate) and would probably absorb a lot of the fluids and keep the odor down.
I was thinking that ag lime would cover some of the smell, but apparently it can delay decomposition in shallow burials: http://archlab.uindy.edu/documents/theses/ThewHAAbstract.pdf
Your question made me go looking and apparently this is an active criminal forensic topic. Who knew?
