Adding a new description is easy, in particular if it is proprietary, see the top of: http://www.dns-sd.org/ServiceTypes.html > I wonder if it might be possible for "us" (Intel, Nokia, Synthesis :-) > to define such a spec for Bonjour-based SyncML service discovery and > try to have it standardized?

If we pick a neutral name (not SyncML or OMA-DS), then I guess we can do it without OMA getting involved. But we should also drive a discussion with the OMA consortium to get this ratified by them. Intel is a OMA member and I know who our representative is. I suggest we write up a proposal and then approach OMA. I can do both sometime next week, if you want. > Given that there's also a wide area version of Bonjour/dns-sd, that > could be huge for non local HTTP as well.

Agreed. -- Best Regards, Patrick Ohly The content of this message is my personal opinion only and although I am an employee of Intel, the statements I make here in no way represent Intel's position on the issue, nor am I authorized to speak on behalf of Intel on this matter. _______________________________________________ SyncEvolution mailing list [email protected] http://lists.syncevolution.org/listinfo/syncevolution
