That's good advice. I am thinking primarily about using this for myself or maybe myself and one other person (once I'm out, anyone else who wants to follow my example is welcome to). The building I'm currently working in is 6 stories, but I would like a solution that would be practical in a variety of buildings since my work will be changing soon and will probably take me to a variety different worksites. I also wan't something for hotels, so flexibility would be good.<br><br>
