Kottke.org has discovered some interesting comments posted on Slashdot by someone who claims to be an Apple employee. The employee describes how Spotlight will evolve in the future with concrete examples.

Here's the most impressive :
You're doing a multi-party teleconference. A recording is made of that teleconference (each angle), and separate audio tracks are recorded for each participant. In real time, your computer transcribes each voice track and stores it as ancillary content on the recording, content that Spotlight indexes for you. At any time, you can type "meeting in San Jose" into Spotlight, and it'll take you right to the angle and track on which your co-worker Laurent talked about next week's meeting in San Jose.

And here's a second :
"Take two files, any two files. Say it's a PDF representing an invoice and a Photoshop file representing a poster you designed. You drag the invoice over the Photoshop file and a marking menu appears, giving you the option of establishing a relationship between the two files. If you want you can annotate the relationship. If you don't, you don't have to. The computer will simply note that a relationship exists."

Time will tell if this is true, let's hope that this year's WWDC will already learn us more about Mac OS X' future releases.
