I think rather than put something like that up and have all sorts of assumptions come to mind, it is better to address these after you've had a chance to open up a dialog among yourself and the potential client. This way you guys can have a proper discussion with all the proper expectations on both sides rather than have all sorts of misunderstanding or misconceptions.

In your example, dating a rock star who's away for months at a time is something you certainly want to know, but having that on her dating profile without giving yourself the opportunity to get to know her by making your own assumptions or to see if this might even work in some other capacity is leaving stuff off the table that in end might have been doable. Just saying.
