MS Key Management Service network requirement?

[Cooky]

Our server team is setting up the Microsoft Key Management Service (KMS).
I found some docs on microsoft.com regarding the ports needed for communication.
However, the documents don't tell you how much bandwidth each PC/request would take up.

Does anyone happen to know the bandwidth requirement for this application?

I have it running on a 2k3 server and the bandwidth usage falls neatly in to "practically nonexistent." I believe it is about 250 bytes / host + framing + and the occasional discovery packet (seems to be once per boot up.)
