(defmacro pub!
  [coll port-key val]
  `(cljs.core.async/put! (~port-key (:channels (meta ~coll))) ~val))

(defmacro sub!
  [[coll port-key] & body]
  `(go! ;; this is just an infinite (go) loop, waiting for stuff to be pushed onto the channel
    (let [~coll (cljs.core.async/<! (~port-key (:channels (meta ~coll))))]
      ~@body)))

;; how i'd like things to work :)

(defview datagrid-body [coll]
  (sub! [coll :sort] (dommy/replace! (sel1 :tbody) (datagrid-rows coll)))
  [:div.table-scrollable
    [:table.table.table-bordered.table-condensed
      (datagrid-columns coll)
      (datagrid-rows coll)]])

.. elsewhere, trigged by click perhaps... 

(defn td [coll attr]
  (pub! coll :sort (sort-by attr > coll)))

So my question is: How do you think I should go about preserving metadata on the coll, like the list of channels, remote url, etc.
