First video you posted he says at 39 - 40 secs into the video each snake will have its own big enclousure in a month or something like that. Didn't watch the second one yet. But if you really wanted to do it you could always email the people who are doing it with success asking them what their opinions are on doing it since they will have first hand experience on the pro's and con's of doing it.
Watched the second video and in that video by the way he is talking those boa's are breeding.
