just thought i would add..... well i found this so it isn't my quote but yeah i agree with the followiung statements...
In bandwidth, cable is king: With the exception of fiber optics, there is no faster way to send a data stream from one location to another. In my tests, I've seen instantaneous speeds of 7 megabits per second over my cable modem -- that's the underlying speed of the data channel between my house and the next router on the network. Of course, I don't actually see 7 Mbps in my daily use. When I transfer more than a few packets of data, the cable modem is programmed to slow down the rate of transfer to roughly 600 Kbps. This prevents me from taking more than my fair share of the available bandwidth.
