Awesome idea, I didn't think of that. It's still not working on my server though, I must be missing some packages. It's just outputting a bunch of 1's for me. And I don't really have the ability to install new packages on my server, that's another reason I wanted to find a way to generate bitcoin addresses without installing bitcoind on the server. I tried grondilu's Perl modification which removes some dependencies, but no luck. I must be missing the dc/bc package. Looks like I might have to read up on the process for creating bitcoin addresses and write a pure PHP script.
