Hi James,
Welcome to the group.
I encourage you to check out this previous post and other messages in
the thread:
http://groups.yahoo.com/group/papercreters/message/2179
Scroll all the way to the bottom of the message to see other messges
in the thread.
While you're likely already aware of many factors discussed there,
some of the discussion applies to your situation and may be helpful.
Reminders on things you already know can't hurt either.
Perhaps Ken from WI will give us an update on his progress. The two
of you are undertaking a similar project.
Hope this helps
