I think people forget that just USING Bitcoin, even it it's just for saving money on a wire transfer, can benefit Bitcoin because it shows people that Bitcoin can be used for easy and (most importantly for a lot of people) cheap transactions. Take the first step so Bitcoin can gain a foothold in Pakistan, then worry about using it as a currency later. I think people already mentioned a couple of exchanges that might work.
There's more to that. There are a few remittance companies started recently (who use bitcoin as transfer tool), if they manage to grab a significant portion of the market - the volume of trade should noticeably increase, which will reduce the volatility and make price manipulation much harder. That's a big thing.
