Is it just complicated, or is it also prohibitively long-running?

If just the former, you could maybe bundle the setup into some shell
script and source it in each of your sh source blocks.  Eg:

#+BEGIN_SRC sh :results output :dir /ssh:lycastus:/home/bviren
  /bin/pwd
  echo $HOSTNAME
  ls -l foo.sh
  echo "---"
  cat foo.sh
  echo "---"
  source ./foo.sh
  echo $FOO
#+END_SRC

#+RESULTS:
: /home/bviren
: lycastus
: -rw-rw-r-- 1 bviren bviren 16 Nov 18 10:27 foo.sh
: ---
: export FOO=bar
: 
: ---
: bar



If the setup is purely environmental, and it takes a long time to
perform, maybe you could do the set up once and then cache the resulting
environment using the output of "env".
