But at that time I was able to take advantage of Adobe's beta version of Lightroom, which is a really nice application. However, I don't really feel like plunking down 300 clams for it, so I was feeling a bit at a loss not being able to preview images I've taken raw in a virtual "light table" so to speak.
But then - ah, I took a closer look at an app I've had since purchasing Adobe's CS2 bundle a little over a year ago. That's right - the Bridge. For a version 1.0 application, it is surprisingly robust and fills in nicely as a virtual light table, metadata and asset management app. I'm able to browse through all of my raw, .crw captured image files, along with being able to see previews of other file formats, like .indd (InDesign) and .ai (Illustrator). Awesome. You can even do a slideshow of a multiple-page InDesign layout, and leaf through the pages of a PDF.
Below is a screen capture of it as a Finder Window on steroids -

And then as an image browser -

And finally, as a light table -

It's quick to simply select an image then turn on 'filmstrip mode' by clicking at the bottom right of the window to view a large preview of the image or file.
There are a bunch of different workspace options to choose from and the windows can be tweaked quite a bit. You can have multiple browsers open at once, they can be made compact (or ultra-compact) and float over all other open windows to use when dragging files into other open files. Snippets and files of all types can be simply dragged into an open InDesign layout while designing. Metadata can be added and processed in batches of files, then searched with up to 13 different specific criteria. Photoshop actions can be run straight out of Bridge on a batch of image files, as well as a nifty little script called the Image Processor, which can do a ton of different things to an image or a pile of images - a great little tool for taking hi-res, raw images and quickly (and automatically) batch-processing them for uploading to the web, like for Flickr. After, of course, batch-processing them with saved subsets from Camera Raw.
I heard yesterday from an Adobe-insider contact that Bridge will be ten times more robust in CS3, not that I'll be buying that, either. But I'll be using it at work. Have to get myself out of the Finder mode on the Mac, and the only really hindering aspect is there is no 'column' view in Bridge as there is in Finder, so that will take some getting used to.
It's not Lightroom, but combined with Camera Raw it's a pretty powerful tool. And here at home, I'm excited once again at being able to do what I thought I couldn't. And all without ever having to open the lame-duck iPhoto again!
