14. The projection system of claim 10, wherein the electronic memory device comprises an electrically alterable memory having a first write-protectable portion configured to provide the information identifying a source for the replaceable components and a second writeable portion configured to store an operations log during operation of the image projection system.

15. The projection system of claim 10, wherein the replaceable component comprises an illumination source for the projection system, and wherein the electronic memory device comprises a memory integrated circuit physically coupled to the illumination source.

16. The projection system of claim 10, wherein the linking portion comprises only two electrical connections.

17. The projection system of claim 10, wherein the linking portion comprises an RF link.

18. The projection system of claim 10, wherein the projection system includes sensors configured to assess operating conditions associated with an environment in which the projection system is operated, and wherein the electronic memory device is configured to store data representing the assessed operating conditions.

19. The projection system of claim 10, wherein the projection system includes sensors configured to assess operating conditions associated with an environment in which the projection system is operated including ambient lighting conditions, and wherein the electronic memory device is configured to store data representing the assessed operating conditions.

20. The projection system of claim 10, wherein the electronic memory device is configured to provide data indicative of a sales channel for a replacement for the replaceable light source.

21. A replaceable projector component for use in an image projector system, the projector system having a control portion for controlling operation of the projector system, the replaceable component including a memory integrated circuit including a first write-protectable portion configured to store information prior to installation of the replaceable component in the projector system and to write protect the information after installation of the replaceable component in the projector system and a second writeable portion configured to store data during operation of the projector system.

22. The replaceable projector component of claim 21, wherein the memory integrated circuit is configured to provide at least a portion of the information identifying a reseller of replacements for the replaceable projector component.

23. The replaceable projector component of claim 21, wherein the memory integrated circuit is configured to provide at least a portion of the information identifying a part number for the replaceable component.

24. The replaceable projector component of claim 21, wherein the replaceable projector component includes an illumination source for the projector system.

25. The replaceable projector component of claim 21, wherein the replaceable projector component includes an illumination source for the projector system and the memory integrated circuit is physically attached to the illumination source.

26. The replaceable projector component of claim 21, wherein the replaceable projector component includes a high intensity light source and the memory integrated circuit is physically coupled to the high intensity light source.

27. The replaceable projector component of claim 21, wherein the replaceable projector component includes an arc lamp bulb and the memory integrated circuit is attached to the arc lamp bulb.

28. The replaceable projector component of claim 21, wherein the projector system includes one or more sensors configured to measure aspects of an environment in which the projector system operates and wherein the control portion is configured to write data corresponding to sensor output data in the memory integrated circuit.

29. The replaceable projector component of claim 21, wherein the projector system includes one or more sensors configured to measure aspects of an environment in which the projector system operates including ambient lighting conditions and wherein the control portion is configured to write data corresponding to sensor output data in the memory integrated circuit.
