You can use the :session header argument which will give you access to
any variables created during the session:

http://orgmode.org/worg/org-contrib/babel/languages/ob-doc-clojure.html#orgheadline13

You can pass the function results to a variable argument, which makes
possible chaining (see http://www.jstatsoft.org/v46/i03):

#+header: :var x=myfunc(2)

You can also embed and call a function in a source code block using noweb
syntax:
