So it looks like there's a common dive profile interchange format called UDCF, and some converters available between Suunto format(s?) and UDCF, if I can now figure out how to get profiles off the watch in Linux. The linuxdiving.org site is linked a lot, but seems to be down. Hopefully I won't need to use a USB sniffer or something.

David, Frank, Whitaker, and I are going diving tomorrow morning, early. Tiffany will be watching the dogs. Dina's still in Portland for her dad's surprise 60th.
