Protocol design also allows requests to graphs (hence, Bryan's point
about resource-centric apps and the possibilities of clash):

/foaf.rdf?key=value

isn't something I can find an example of this minute, but I'd be
*astonished* if there are NO implementations like this. And if there
are "query" and "graph" and other generic terms seem ripe for
clashing.

Yes, but that ignores the resource and graph centric "way" of the Web
and implementation strategy. It's perfectly legit, and I can't ignore
it.

Again, we're dealing with resources AND services, not one or the
other. Clashes seem much more likely w/ resources than services.

I'm concerned even if we can't find an example *this minute*.

Ah, yes, of course. How stupid of me.

Why quantify? Do you mean there's a threshold of existing possible
clashes that you require before this is a "real" issue? How high is
this threshold?
