Apple purposely designed it that way to make it more portable. I think that we can use the ordinary dns-sd DLL (instead of writing a wrapper), and have it talk to the native server instead of one running inside Wine because of this. Chip

I would assume that applications bundle a version of dns-sd because it's not a Windows dll. If that version cannot be used for some reason then we can think about adding a wrapper.

One question about making a Windows service: would the programs still be making calls to the DLL? Or would the be making calls to the service? If they're making calls to the DLL, wouldn't something be needed to route those calls to the OS-native dns-sd implementation? Again, forgive my ignorance on this subject :/

No, it now succeeds in starting Bonjour, even if there's a native mdns server running (see comment #36). The problem is that when Bonjour finds that it can't do a wildcard bind it binds to specific addresses, thereby stealing traffic from the native server. We should investigate if the native server can be used by Photoshop. Then we could write a stub Bonjour service so that Photoshop will not attempt to install its own version. There's no need for a dns-sd wrapper dll in this scenario.
