I should note as well: having a channel technology named "sendMessage" would be
silly and would be a highly non-standard channel technology name. Further, we
don't support a PUT operation on a channel technology via the endpoints
resource: what are you PUTting? Even if we support dynamic endpoint creation
(which would be cool), that would most likely be a POST to
/endpoints/{tech}/{resource}, which still avoids any collisions here.
