At the parties of DJ Thomas Gylling, who plays Soca, Dancehall, Reggaeton and other caribbean music at large upscale clubs in central Stockholm, the reverse is largely true. Here's a video montage of some crowd photos - there are probably a couple of diasporadic Trinidadians and Jamaicans in the crowd, but I'd guess not many. The majority are middle-class Swedes, some of mixed race, most white.
Now, I'm not going to tiresomely go around and try to argue that this is all somehow wrong. It's inevitable, considering the different cultures and classes involved. But what I do wonder is - why isn't there more exchange of DJs between the two club forms?

And as for the opposite, DJs who regularly do diasporadic events doing mainstream club nights, that's unheard of too, no matter what kind of music is played. Sweden has loads of interesting clubs playing non-european music, like Re:orient Club. Looking over their DJ roster you do see non-swedish DJs but none of them are from the same set that would play your local Lebanese night. No, names like "DJ Shazam" and "DJ Cheb Oman" belong to white europeans, not arabic immigrants.
It seems that deeply entrenched diasporadic DJs just never get to play to more mixed crowds in different settings than the diasporadic one. And I'm kinda wondering why. How come you never see someone like DJ Oslus DJ a party of largely college-educated white kids? If you're after knowledge of African music surely someone like that would be a good choice. Are they not good enough? Don't they send out the right kind of hipster signals?
I think there's a deep inherent danger in only allowing middle-class DJs with existing access networks to present music from the developing world. The DJ is a story-teller and manipulator and can form the discourse concerning a musical style at will - are we only ever going to hear one side of the story at party nights? I do realise that bringing a new audience and revenue stream to people might alter what they play for the worse. But is it worth the risk of one-sidedness in transmission and translation?
If Mr. Nice ever does come back to Stockholm I'll try to go see him, whatever the venue and however uncomfortable I'd feel. I'm keeping tabs on the community now through the Kenya Stockholm Blog. But wouldn't it be awesome if some club promoter would have the courage to bring him and his DJs to Berns instead?
