... Ok, here's what we've found so far.
A) Yes, there are tons of registry values. However, though the key is STORED in the registry, it is only used for CHECKING purposes. Also, most of the changes to the registry occur during installation. From my checking, I've come to believe that there are little/no changes during activation, and, if there are any, they are not important enough to warrant further search.
B) No, cracking the paul.dll will not help. According to psychophat (please correct me if I'm wrong), the paul.dll file is a series of calls, with error messages and confirmation sequences if certain benchmarks are met. Unfortunately, while hacking that will PROBABLY be critical in the main release, it's no longer one of our top priorities because the confirmation happens AFTER the paul.dll is used, so altering it would not benefit our purposes (unless you want to never play the game, in which case, just delete the whole file!

)
C)There was one other solution posted relating to a file called ra3game.dat. Yes, the file is critical to the game. No, from my understanding of other users information and my own research, I believe we reached the conclusion that the ra3game.dat file was not worth being hacked. If you want a soviet Akula sub to work properly, then you'll need this file. If you would rather attempt to play the game with a messed up file... Well, the Allied peacekeepers would be flying units for all I know. I think that wouldn't exactly be what you're looking for
Edit: (Please note that the Akula and Peacekeeper comments were made in jest. The real information pertaining to the units data is stored in .big files. We just don't think that messing with the ra3game.dat is worth our time, based on its use in game).
Currently, we (by which, I mean me, considering that I don't know what psychophat is doing) are trying to track down missing files that registered users may have that we don't. Maybe we'll revisit the idea of cracking the paul or altering the ra3game.dat(though I doubt it), but either one of those ideas are USELESS if we don't have the files necessary for game play. Please understand, we're not lying through our teeth. We want to play the game just as much as you guys do! But we're going to need a bit more time.
And, kameleon? I think you've just solidly damaged the game. You've got errors in the ra3game.dat, and that's not going to make it work... Oh, and emulating the EA servers has a VERY low chance of success, because EA downloads files to your computer when it registers. If you don't have those files, you won't be going anywhere.
