Advertising BGP-4 from two islands

[francois at menards.ca (Francois Menard)]

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...
