The side effects/seriousness of insulin is way overblown, unless you are an absolute idiot, which there are a lot of them out there. It's amazing how many people don't know how to measure iu on an insulin syringe, hell I know a guy that took a full 3 cc syringe of Humulin R because he didn't know what the hell he was doing, and he's still with us. So it is REALLY hard to kill yourself with skin. If you do happen to go hypo, it's not like you don't feel it coming on. It's not like Bam! and you drop over dead. Anyone using slin should have an immediate source of sugar close by at all times just to be safe.
