Thanks, but it's more a resource/time issue... The current version of the CopperLan Manager was designed around 8 years ago and needs a huge refurbishment
But the CopperLan code is cross-platform, based on basic low-level APIs who are not about to change anytime soon. We don't use any MacOSX particular feature, so I'm confident that it will continue working until next big generation step (such as we had when Apple decided to drop PowePC architecture).
