I think you have good idea but the biggest problem with it is just flat out people being people: that being there are always going to be blatant idiots that go "Ooohh snake I'm gonna buy it" versus the (thankfully) majority of us that do the research and understand their requirements before taking possession and care of the animal.

I agree with the common sense thing too... if even without any research at all you're still too dull to realize that 2 different animals that come from 2 different continents and ecosystems (and even as a 2nd grader I had enough common sense to see the difference) yet still decide to house them together then you're just asking for it; especially if you only start to question your decision and seek help after a problem had arisen from it. Remember: True idiots have to be told and proven they're idiots before they might even start see it. (I just made that up, feel free to quote it; duty free )

And even with the live feeding I'd be willing to bet that there are more people that keep a single snake (probably poorly) and feed it live because "Durrrr my snake just kilt that there rat" than even the majority that do it responsibly and have the live feeders available to make it a convenient alternative. Even between my gf's and my collections we only have to feed 2 live and I consider it a pain more than anything because I don't want to keep enough rodents in our current place to even sustain that. So when either of us aquires a new snake and it takes F/T we consider it a win.
