I'm not doing well for trying to think like a newbie today, but how
about:

from a menu item "adjust quality" you'd get a dialog like this:

|----- Vorbis Encode Quality -----|
|  Quality:                       |
| 0 . . . . . . 5 . . . . . . 10  |
| ---^--------------------------  |
| Vorbis quality <box w/ up/down> |
| Equivalent MP3 bitrate (approx) | (then another box, wouldn't
|   < OK >            < Cancel>   |  fit in my ascii art)
|---------------------------------|

Then the user could set a quality with a slider or by number, or input
an MP3 bitrate and get a roughly equivalent Vorbis quality. Updating
one thing would immediately make everything else update also. This
would require a simple function to map qualities to MP3 bitrates, but
I think somebody could come up with that (you're only hoping for
approximate anyway) and it would give new users a much better feel for
the kind of audio they're getting from a certain set of settings.

Maybe consider including the expected Vorbis average bitrate, but that
might be too confusing since it's just an educated guess and also
since there's another bitrate in the same box.

I'd agree with whoever said OggDrop should only do VBR. For streaming
you'll probably have a more advanced system set up, or when peeling
gets implemented the streamer can peel the rate down. For everything
else, people might start thinking like MP3 or old Ogg and just enter a
bitrate without realizing quality works better, then we'd have to bug
them about it.
