Thanks, youre a rockstar, I was even gonna send 2 with the tip for helping. Ok now that I've got it figured out, there's only one big problem with making these. Trust. So far only the latest Bitcoin uses two-key address creation, so the vanitygen makes an address and the one privkey that you import with the wallet in the Console. Anyone would just have to trust me that I wouldn't later try to import the privkey and use your coins. You can always transfer them right away to another address if you're paranoid.
So I don't expect any takers. That's cool. But if anyone is interested, it looks like I can make custom addresses. I made a ton of other coin addresses for people so far in IRC with no problems. Believe me I don't want your coins, I like to mine hard and earn my own. Now for the difficulty, as you might imagine if you know computers, it gets much more difficult to impossible to make bigger customizations.
Making an address that starts with just "GPUC" took about 1 minute for the generator, and has a difficulty (diff) of 78505 (yes you're reading that right 78k diff). GPUC1 or something took about 10 minutes and has a difficulty of 4553521. See how it's getting harder? Now GPUCS1 has a difficulty of 264104224 and will take an hour to many hours to generate. My 1Anthro BTC address took all night to generate, just for reference.
So if you want a custom address and trust I won't take your coins, it'll be 5 GPUC coins for a "GPUC" or "GPU1" type address, 10 GPUC coins for a "GPUCS" type 5 digit address, and 15 coins for a "GPUCS1" type 6 digit address.
Not all prefixes work, like Guuud won't work, but the ones I listed do and I made them.
Let me know, or not, idc
