All I can offer is some annoyance with the first post that popped up in the egyptiandreams link you provided, claiming that the Egyptians would not have taken the wax from hives if bees and honey were a luxury item.

This particular claim is patently ridiculous. Until very recently, harvesting honey from a beehive meant destroying the colony of bees because of the design of skeps -- now hives in the US, for example [not because other parts of the world do not use these, but because using a skep is now in fact illegal in the US in particular], are designed to allow the beekeeper to cut and harvest the honey from the hive without damaging the wax or injuring the bees. Indeed, it is largely because of the decline of the price of honey and the reduced profit margin in raising bees for honey that it has become so important to improve yields by not disturbing the wax structure, which requires a significant caloric output by the bees to restore -- which is why I find it annoyingly difficult to find a good honeycomb anymore.

Again, however, I apologize that this is more a quibble with the links than any profound endorsement or refutation of the larger arguments involved. I do always recommend some extreme levels of hesitation when archaeologists want to identify anything as death/rebirth symbolism, since this often seems to be an unfortunate default for a career that involves so much trying to understand cultural values through the lens of funerary practices.
