Format Battle: OGG (audio)

http://en.wikipedia.org/wiki/Ogg

Ogg is a free, open container format maintained by the Xiph.Org Foundation.
The creators of the Ogg format state that it is unrestricted by software patents[2] and is designed to provide for efficient streaming and manipulation of high quality digital multimedia.

"Ogg" is derived from "ogging", jargon from the computer game Netrek:

3.3 Ogging: This is the art of killing a carrier, or potential carrier, by a suicide run.[3]

I’ve been wondering who uses OGG and what bitrates they expect from an OGG encode.
Assuming a lossless source only.
(game rips exluded; as game rips should be extracted as-is if already OGG format)

I use Foobar2000 which has its own "encoder pack".
It has a maximum of 500 kbps (q10.0).

I’m pretty sure that would be closer to AC3@640.
It’s pretty high and much more efficient than MP3, I’m sure.

What would be the average bitrate you would want for an encode?

Going in whole integers (1.0) for increments:
~128 (q4.0)
~160 (q5.0)
~192 (q6.0)
~224 (q7.0)
~256 (q8.0)
~320 (q9.0)
~500 (q10.0)

Is q10.0 (~500) compliant for the devices you use to playback OGG?
Or does it break above 320 (assuming MP3-type standards).

I require feedback on what you use for bitrate.
