Su Ling... have you heard of "Internet Number" from Japan? <a href=http://www.gmo.jp/en/press/release/20040323.html>http://www.gmo.jp/en/press/release/20040323.html</a> <a href=http://www.888.ne.jp/biz/index.html>http://www.888.ne.jp/biz/index.html</a> Here are some notes from the PWG meeting where the PWG discussed your material. While we can relate to your use cases and understand the benefits for devices with limited (numeric only) keypad, we were not exactly sure what you feel needs to be standardized in your scheme. We are guessing that you feel there is a need to standardize the protocol between the printer and the PNS, and, maybe, the means for a device to register with the PNS (for example). Is this correct? Here are a list of questions that were asked during the discussion. You do not necessarily have to provide a specific answer to each question right now... this just gives you an idea of the level of understanding achieved at the introductory meeting. I urge you to consider joining the PWG or, at least, attend the April meeting in Tokyo if you want to help the PWG pursue this further. Also, it appears there may be other companies already pursuing this idea. If "Print Number" (or "Internet Number") is to become ubiquitous, there may be a real need for some standard interfaces in this space. <ul> <li>What is the namespace?  Is this a world-wide service? <li>What is the process for assigning numbers? <li>What is the lifetime of a PNS number? Scope? Duration? Are PNS numbers intended to be durable while URLs may change? <li>To be unique and durable, numbers will have to be very long. At some point, very long numbers are harder to recall and deal with than URLs. <li>(e.g., IP numbers vs. DNS names) <li>International issues (numbers are inherently global, URLs are not). <li>What is the protocol between the printer and PNS? <li>How do devices register with the PNS server? <li>Case 2 seems like “follow-me printing” already done by (ex PrinterOn). <li>What are the security / authentication requirements? Public vs. private documents. (e.g., random print number entry) <li>The documents explain well the benefits.  What are the costs? (random "dialing", security, wrong number prints large document) <li>What do you already have working? <li>In particular environments, the idea might be useful. <li>“Print Number” (the company) should participate in the PWG to move the idea forward.</ul>---------------------------------------------- Harry Lewis IBM STSM Chairman - IEEE-ISTO Printer Working Group http://www.pwg.org IBM Printing Systems http://www.ibm.com/printers 303-924-5337 ----------------------------------------------
