On USTREAM.tv last year there were 2 or 3 webcams aimed at BO(?) eggs with windows cut, pre-pipping stage. There may be this year, I haven't checked in a few weeks. Such that you could watch the developing snake. I'm guessing the point was to have the eggs on webcam, not scientific or other 'academic' purposes.
I'm clumsy and a worrier...I wouldn't want to be compromising my young snakes or their eggs. But obviously I will tune in to watch if someone else (surely a more experienced expert) does it. For me, watching the snake eggs is an elegant alternative to watching a bazillion litters of shiba inus, golden retrievers, and yorkies....'do their daily routine'.
