Well, now I feel completely stupid.

And I poured through Pentax's site looking for exactly that type of software...

I guess it's because my searches never included the word "assistant."

I believe I have the latest firmware, though I'll doublecheck. It seemed really silly to have a USB connection for downloading pictures only...

I'll have to give this a try, it'll just have to wait a few days (hopefully the Remote Assistant is Vista compatible)...
