As some of the posters above have pointed out, 7260 was the last leaked build to still support RC/beta keys--7264 is the one where that's not possible.
The only legal way to keep it going until Windows 7 is for sale with legal keys is to use the rearm method.
Nitpick: If you want to get technical about legality, then the rearm method is just as illegal. The 30-day activation grace period is not meant to be used as a "trial period". Nor is the rearm meant to be used for anything other than returning the system to a clean activation slate by OEMs for preinstalls or install imaging. Use the rearm to extend the grace period is technically a violation of the license agreement and thus technically illegal.
