Done. Thank you for the suggestion.
A new release of dot2tex, version 2.8.7 is now available for download.
You can see the full release notes here:
http://groups.google.com/group/dot2tex-users/browse_thread/thread/39901faaf5b5aa4d
I have not documented the new feature yet, but I have implemented it
as you suggested:
dot2tex.dot2tex(dotdata, format = "positions")

The tests now run if all the dependencies are available. I fixed a bug
that prevented the poltab example from compiling.
