After reading a bit more on the use 507 status code I'm still concerned that this is very much related to Storage and would not be broad enough to encompass all the of the scenarios that we have (bandwidth quota violations, storage violations, application object quota violations, etc).  It still seems that a more general status code is needed.

Now, to Robert's earlier mention of the use of 403.  The concern there again is still the idea that people will confuse this with the password issue.  I appreciate that the spec does call out that the request was correctly formed, the server understood the request and that the reissue of the request will have no effect but in practice most users, IMHO, will simply only check their passwords.  I think the fact that we see so many other services not using 403 for this sort of thing supports this conclusion.
