At present there are less than 30 countries developers can submit Windows Phone 7 apps from, leaving a lot of talent on the table.
Microsoft realizes this, and have created a new Global Publisher Program which will allow developers from all over the world to submit applications using intermediate publishers.
An example is Yalla Apps, which will accept submissions from developers for a $99 registration fee, just like Marketplace directly, and require only a PayPal account rather than credit card and bank account.
Of course other developers may want to benefit from this ease of use also, but unfortunately the service is not available for developers in countries where Marketplace has launched already.
