I do not know what your connection speed is. But I have done speed test from around the world. I have a 750KB/s connection and the slowest speed I get is 350KB/s which is still pretty fast. You may want to do a speed test and see if it will make that big of a difference. Because you will defiantly be limiting yourself on sources. The link below has Internet speed test sites from around the world. Not all of the work but most do.
