Most grid uses these days are "compute" grids. As we start to look at some other interesting concepts of "grid" usage one that has been mentioned has been the "display grid". However, as I think about this it seems that the term really spans a continuum of possibilities.

Is it a DISPLAY grid ... or a display GRID?

DISPLAY grid to me implies that the primary usage/focus is around the concept of "display". Whether that is a web browser based environment to a single/few selected apps to a fully blown desktop environment. The focus is on the interactive usage. The grid portion than gets brought into the concept in two ways. First, the architecture used to deliver the display functionality could/may be based upon common grid architectures. Second is that there is a desire to use unused cpu cycles to do "tradional" grid computing tasks. This scenario would be typified by things like ... delivery of web based kiosks or "simple" web based vertical solutions.

display GRID than is the total opposite of the first scenario. The primary usage/focus is around the grid computing aspects and that secondary to the grid computing might be the display of the results of the grid computing tasks. This scenario would be typified by things like ... animation rendering, molecular modeling, dna sequencing etc... You might want to be able to display from the grid simply because the volume of the date is such that moving it would be tedious, or, it's a very iterative/interactive process that the user is involved in.

That's my thoughts... what do you think?
