I feel your pain.
I ended up cobbling together a dock of sorts from a small powered speaker system and a Bracketron clamp-style mount that I attached to it.
I piggybacked a USB power adapter onto the speaker's power to reduce the number of power plugs to one.
It's been pretty good so far. I use it at with my Droid Bionic at work where I stream Sirius and Pandora all day.
I know putting something like this together isn't for everyone, but it shows what lengths folks well go to to have something that works in a similar way to all these obscenely convenient iPod docks.
