IPS is actively exploring options for video. There's no news to share (yet!).
I'm personally a big fan of video and imagery as a growing form of communication for the future. We invented text because it simply wasn't possible to replicate in-the-moment images that captured the entirety of the experience in the times of cavemen. We needed to use sticks to draw representative pictographs. We're now coming full circle. With cloud storage, cameras, smartphones, and instant photography available to the masses, our communication of the future will be richer, more full bodied, and all-encompassing. Textual conversation in forums will always be the legacy focus of IPS, and I don't think that's going to change, but it's clear that a significant portion of online communication is moving away from text and towards voice and video, and it's not a trend that will reverse.
As others have astutely pointed out, IPS needs to explore options that can work across the range of communities and server hosting environments.
