About the lime: my obsessive compulsive disorder drove me back to the Red Cross publication mentioned above to resurrect (sorry) exactly what they said about lime use. It was in the FAQ section at the end of the publication, and as usual with brief replies, raises more questions than it answers. At any rate, I quote:

"4. Is spraying bodies with disinfectant or lime powder useful?

No, it has no effect. It does not hasten decomposition or provide any protection."

I hope this buries (doh!) the issue once and for all. ;-)
