It took Apple 2 years to support MMS, and in The States, it took AT&T about another 4 after that. Think about the message it would send if shortly after the n900 release, the community implements MMS. We can build and flash our own kernel (I hope). Maybe it's an OSS blessing in disguise. This kind of thing could attract developers and consumers. And if I've been reading the MMS threads correctly, I think it already has.
