It looks like you've inserted an orgmode specific function into slime?
Maybe your slime patch could be changed to the introduction of a new
hook to which this org-mode specific function could be bound? I imagine
the slime mailing list would know the best solution here.

I think it is reasonable for the :session header argument to be added to
an `org-babel-default-header-args:lisp' variable defined in ob-lisp.
That would remove the need to constantly specify :session. This is
similar to the ob-clojure approach, which by default always uses a slime
session.

Great, I look forward to playing with this as soon as I find some
time...
