Of course we'll entertain the topic here... but if it were as simple as just spoofing the files/setup/connection it'd have been done already unfortunately.
From what I gather, more likely someone will compile and leak an illegal PRX (built with the official $DK) and it'll be used to reflash the BiOS, not necessarily with "v1.00" but perhaps with a modified BiOS. That's how the UMD dumps were done... using a utility compiled to run on a retail PSP created from the official $DK. Of course a more LEGAL "homebrew" solution would be safest/more desirable to dev'ers, but I have a feeling most end-users will take any method they can to get homebrew stuff running on their PSP. I'm not saying the "spoof" idea is impossible, just that there are other ways to accomplish the same thing (without messing with http://www.cr0.net:8040/code/crypto/aes/ and the related hurdles) that are currently being worked on to reflash the PSP BiOS.
