[2]This separation is not absolute. For example, a television is used in conjunction with a settop converter for display of both over-the-air and over-the-cable signals.

[3]The Modified Final Judgment governed the break-up of AT&T.

[4] Similarly, we hypothesize that O(C,^-)O(G,^-)D is not stable in the absence of regulatory forces.

[5]Of course, the properties of the channel may determine the rate and timing of that flow. However, temporal decoupling can be leveraged to provide many interesting tradeoffs.

[6]For example, traditional telephone systems allocate fixed bandwidth for the duration of a call. Packet data systems (and some digital telephone equipment) dynamically adjust the bandwidth allocation during the transaction (or conversation).

[7]Software includes computer programs and "content" (e.g., movies, databases, etc.).

[8]Our colleague Danny Cohen made roughly this observation many years ago in a discussion concerning universal addressing schemes.

[9][21] proposes a SpectrumWare environment in which wireless appliances use software-based components to support a range of coding techniques.

[10]Thus ensuring that the channel is safe, in the terminology of Section 1.5.

[11]Mitch Kapor has suggested that some interoperation issues may be addressed through a changed business ethic that treats those who resist interoperation as pariahs.
