Punx, the only thing that concerns me about that scenario is that if you have one dream system, with one person who is an extremely skilled overclocker, that person could do the initial benches on that machine, then send the entire system to the next guy on the team along with the settings he or she used, then after that person is done posting very similar results, they send it to the next guy along with the settings, and so on and so forth. If we're talking 2 guys, then not a big problem. But what if you've got 50 guys on a team who use this dream system? Start magnifying the number of people on the team and you realize that you'll suddenly occupy a significant block of the results on hwbot, and more or less own all the points. How would hwbot determine that it was "skill" being used and not the same settings as the person before? Similarly, if a bencher is a hardware junkie, he can give out his systems or components and potentially get a few members of his team points and hardware junkie status too. Hell, what if k|ngp|n loaned out everything he had to the rest of the members of XS? You see where I'm going?
Ok, but let's talk about only transferring a cpu or graphics cards. Same exact argument as above, only less points are at stake. In a perfect world, they should also consider using shared cpu's as impermissible in 3D benchmarks, as a QX over 4.5ghz will have a huge effect on a score over a dual at the same speed.
I see where you're coming from on the recognition part of being a good or great overclocker, but if two people are having similar scores (not identical, but close) from a similar setup, then how will anyone be able to tell that you're the one who overclocked the system by yourself.
But since I think you're talking more about someone buying the hardware and then sending it to someone else to bench, well, this, I believe, is permissible SO LONG AS the bench is submitted under the name of the person owning the hardware. This prevents multiple people from claiming points on the same hardware. While the person benching won't get the recognition he or she would like, the points would be counted one way or another. If you must, under this scenario, put in a note saying "this result was achieved by *****."
