baroni is not going to kill you unless you're allergic.. You just need to be sensible around them (hook, not grab/hold), and if they do manage to bite you for some reason - not let them chew because it's "funny" like what some people do with a hognose. Their venom delivery system may not be that great, but if they do manage to get sufficient into you, it's going to hurt, swell, bruise from finger to shoulder.
Females are a LOT bigger than males (especially in girth).. nice is that you can cohab them, but if you stick males and females together they will breed without doing anything special. During feeding they'll have to be separated. Also they need quite a bit of room (vertical + horizontal). Otherwise, they are easy to keep, active, diurnal snakes.
There's a flickr stream of someone photographing his experiences being bitten by olfersii. olfersii has a better delivery system for the venom, and is a more potent. You can find it here in case you're curious:
