Perhaps we should set a precedent for content-limited servers not to 
advertise themselves as being fully functional WebDAV servers.   That 
would go for those CalDAV servers that can't handle non-event data in 
calendars too, at least that restriction could be advertised on those 
types of collections.  There are probably a couple other restrictions I 
would consider major hurdles for clients expecting to "do their WebDAV 
thing" -- possibly some of the weak or no ETag cases or wierd 
creationdate cases we've discussed before.
