Wow, almost 10 years old thread comes as first in Google when searching on 'Bose serialdata'! Anyway, I'm an integrator of OpenRemote and currently I'm adding Bose protocol to OpenRemote. Results are promising and anybody interested is invited to test it (when it will be released of course). You can find more about OpenRemote project on http://www.openremote.org
For logging my experience with the protocol integration I use the blog [Link: mqlservice.net]
Please note that OpenRemote is free and open source project.
