I'm interested in compiling a list of all the Pythonidae hybrids so people know what is possible, to whom to give credit for the first viable crosses, when it happened, etc. I'm a relative newbie, so I'm sure there are people who have seen, handled and bred these hybrids, so I defer to the greater general knowledge on this. I think it's fabulous that herpers are experimenting with their diverse collections to create new and beautiful forms. And if "God" didn't want snake hybrids to exist, he'd have erected a species barrier like he did for most other vertebrates 
Just a note, I'm not so interested in the sub-species crosses like the various carpet python crosses (though yes, they are beautiful too), I'm more interested in crosses that wouldn't exist in nature because the of the geographical limitations of the respective home ranges. Please add and correct this meager list I've started:
Python regius x P.anchietae -> viable cross
P.regius x P.breitensteini -> viable cross
P.reticulatus x P.molurus bivittatus -> viable cross
P.molurus bivittatus x P.sebae -> viable cross, albinism compatible!
P.regius x Aspidites ramsayi -> viable cross (NERD 2006)
Morelia spilota x A. ramsayi -> viable cross (NERD 2006)
M. spilota cheynei x Liasis mackloti mackloti -> viable cross (NERD 2006)
M. spilota cheynei x M. viridis
M. spilota cheynei x M. bredli
I'd personally love to see a L. mackloti mackloti x P. regius
