it may make it a hassle to prrescribe outside doses, but it can. i've set up shit like this, so please stop,. there are leagal issues that the doctor is worried about far more than any idealistic, romantic idea of a money grab you're concerned about. you're right that the software is VERY VERY restricting and i know many doctors who refuse to use it and they're allowed to, though they have to document what they do in some other way and have someone put it into the computer.
i've dealt with this in both the united states and canada where have you implemented it?
