I think it will be nice to have a more distinct name to activate this skin than "strapping" like e.g. "bootstrapskin". There is at least on other skin around which is activated with the same name. Thus you cannot install and test them at the same time. I think such collisions should be avoided if possible even if there is indeed only a minor chance that this will happen.
Edit: another thing will be to also have consistent naming in the backend like, e.g.
require_once( "$IP/skins/bootstrapskin/bootstrapskin.php" );
since I think this will make administration easier in the long run.
