Cloud-based worship software?

So here's something new that I'm looking forward to trying out: Proclaim. According to the video on the Proclaim Web site, Proclaim runs on Windows or MacOS, and your worship resources are available to anyone on your production team at any time (sounds like a cloud-based app to me).

I definitely like the idea--it's no secret that I'm becoming increasingly weary of our current presentation software package, and I'm generally put off by the high cost of licensing for almost every worship presentation package out there. I like the idea of being able to distribute the production work to different people without the requirement that they come to the church to use the software there.

So I've signed up for the trial, and I'll give it a whirl. If you do the same, I'd love to hear your impressions.
