jeff,
you and your work were not subject to my last mail. I did not mention you nor have you or your work in mind when writing my last mail.
point of contact> Use the mailing lists linux1394-devel@eclipt.uni-klu.ac.at for developer (programming issues) linux1394@eclipt.uni-klu.ac.at for general posts like announcments, non-programming questions. To prevent spam, you have to subscribe to the lists first before posting.
