I believe this doable and can be included for the project. Since the
focus of the project changed quite a bit since I first wrote the
proposal, the goals for the summer had become somewhat vague. What is
written and suggested here might very well help solidify what can be
done for a printing project.
Right now I am afraid that until I complete my university finals next
week, my presence will be low here. However, I will continue to keep
an eye on the discussion.
