ArriRaw Toolkit allows Mac OS X and Applications to work with ARRIRAW “.ari” image sequences. With this Toolkit, Finder is fully aware of these files, including support for Spotlight, Previews, and basic QuickTime Playback. Other applications that are QuickTime aware, will also work with ARRIRAW file format.
It's only $799.00 (all three Glue Tools Toolkits bundled together are only $1599.00). This is helpful albeit I believe a wee bit overpriced since Final Cut Studio itself is only $999 for the full version. But it is cheaper than buying a ton of hardware to do the same thing.
