I don't know that it's an issue of the server being smart enough to adjust the encoded bandwidth to match the client side - so much as it is servers not being generally fast enough to do that on the fly. Hence the need to manually prepare and encode clips in different bitrates if you feel that you want everyone from high speed broadband to dial-up to enjoy your stuff. =)
