Are there any mailing lists specifically about 1-Wire issues?

Yes. Dallas Semiconductor runs a list specifically for 1-Wire software developers (hardware questions are frequently addressed as well). To join this list, send email to majordomo@iButton.com. Make sure the phrase "subscribe 1-wire-software-development" appears in the body of the message (and turn off the HTML formatting on your e-mail - this message is read by program, not a human!). When you sign up for the list, you will get an e-mail that tells you how to post.
