I was wondering how "easy" it would be to have GP2X games/applications talk to a Mac OSX. I know GP uses Linux and Mac uses a variant of BSD. But they're both *nix platforms. So making an application or game that could be loaded on both, communicate with each other and pass data back and forth, wouldn't be that complicated code-wise, would it? Since they both had *nix back-ends, I thought it would be an interesting idea. But I was just curious on how difficult something like that would be. Thanks.

If the GP2X has networking capability, then you can use TCP/IP to communicate with any other system. Most devices like Nintendo DS and PSP have networking capability so possible GP2X has it as well?
