I suspect you will get an increased upload. NTL will have to. A 300K upload would probably not be able to handle the anounts of Acknowledgement packets needed for 10 meg.

In case anyone didn't understand that, TCP/IP (the protocol used for data on the Internet) transmits data in bursts (called "packets"). The server sends several numbered packets to the user's computer, then the user's computer has to send a packet back stating which it has recieved. The server then sends the next batch, and re-sends any not recieved. The server will wait for the acknowlegement before it sends the next batch. It's entirely possible the amount of Acknowledgements needed would swamp a 300K upload, so NTL will probably be upgrading that too.. We haven't been told yet though.
