Rather than require the TQP server to ignore any data received, it would be nice to allow some specification of which temperature(s) (e.g., CPU box, disk drive, outside, operator) is desired. This would make it possible to have more than 1 temperature sensor per IP address. Similarly, the temperature quote returned should identify the temperature(s) reported. :: Jeff Makey Department of Tautological Pleonasms and Superfluous Redundancies Department Disclaimer: All opinions are strictly those of the author.

Here at WRC we've built a networked weather service which has been extremely popular. It consists of a weather station on the roof with a thermometer, windcups, tipping bucket for rainfall, etc. The station continuously feeds information down a coax cable to a PC which exports the "weather service". We have a couple of clients tools for various platforms (Xerox workstations and Suns), which use a simple datagram-based protocol to periodically query the PC "weather server". Turns out there are lots of interesting things you can do with a packet worth of snapshot data from such a weather server. Client tools report obvious things like current temperature, windspeed, etc and can also be smart enough to manipulate the data to draw conclusions like how hard it is raining, wind gusts, etc. (especially important to lunchtime runners in Rochester). We have weather stations (and their corresponding PC servers) currently in Webster and Tarrytown NY, Pasadena, Toronto, Dallas, and Atlanta, with El Segundo and Cambridge, England in the process of installing one. The project originally started primarily because of one (JWright.wbst128@xerox.com) person's interest in weather and remote instrumentation - it is now so popular within Xerox that we've had to work hard with backoff algorithms and ways of limiting the traffic. Monitoring the traffic indicates the weather service has at least 1000 users (most continuously polling the server). There's a lot of weather junkies out there!
