There are many remittance companies in UAE, Saudi & Oman where migrant workers send their salary back home to India, Pakistan, Bangladesh, Nepal & Philippines. UAE Exchange being the major player there. Many of these companies might want to signup for Ripple because they can avoid the middlemen (what if Ripple becomes the middlemen ?) , thus more profits while keeping the fees low for customers and have rapid money transfer rather than waiting days for bank clearance.

The problem in implementing this is the origin & destination country should have legal mechanisms in place to operate this. Many low income migrant workers use schemes called "Hawala" , "Hundi" to avoid the fees charged by the remittance companies.

Maybe RippleNet can work in favor for both consumers and providers. Do keep in mind that RippleNet is not the same as XRP. The remittance houses will have to maintain Nostro and Vostro accounts for funding which I believe is currently maintained in USD. They can switch this to XRP to avoid those transaction fees and overhead.
