Actually I just thought of another not entirely unrelated question. If i use eye one match to create an icc profile for my external monitor on my macpro, can i then drag that same icc profile over the network onto my laptop and use it when i plug the monitor into my laptop as a second display?
First, just to clarify one point, while all the typical RGB working space profiles (sRGB, ColorMatchRGB, AdobeRGB, ProPhotoRGB, et al) are all matrix-based and are all "monitor" type ICC profiles, it would be incorrect to assume all monitor profiles are matrix profiles....they could be either depending on the software used to create the monitor profile. The better monitor calibration/profiling packages will allow you to create either type of profile for your display but LUT-based profiles are typically of better quality and more accurate.
To your most recent question, I would assume that you CANNOT take a display profile from one system and port it over to another, even if both systems are sharing the same display. When you're calibrating/profiling a display, you're profiling a display SYSTEM of which the video card hardware is a part of. When you switch from your laptop to the desktop system, the display hardware is getting changed in the process. The one exception MIGHT be if you're using a display with internal LUTs (Eizo displays and their ilk) where the calibration software leaves the video card linear and only modifies the internal LUTs of the display hardware. Even then, I wouldn't take that chance as it only takes a couple of minutes to build a new monitor profile for the other system.
Profiling a display is not unlike profiling a printer where you're profiling a printing SYSTEM which includes the printer, ink, media and driver settings....a printer profile might not even be portable to another system by virtue of the other system possibly having an older/newer version of the print driver.
