Advertising BGP-4 from two islands

I have an opportunity to launch services in a remote marke, where I cannot extend my backbone to. However, this market is big enough that I can afford to put a Cisco 7201 over there and peer in BGP-4. Do you have any advice as to what may happen if I advertise different blocks from the same AS number, from two different locations, one of which I do not have my own transport facilities to... F.
