Biggest problem I see are service types. service:printer:ipp should be equal 
to _ipp._tcp . Scopes can be mapped to domains, text attributes are similar 
enough.

Well, there is always chance. After quick look at kdeprint code I imagine kded 
module running query for _ipp._tcp and _printer._tcp , adding and removing 
printers as necessary. There is one problem though: add/remove operation 
requires root privileges. Is dialog box asking for root password acceptable 
everytime when someone (un)plugs printer or network cable?
Second problem: I have no way to do any testing: I have no networked printer 
nor computer running MacOSX (I also don't know anybody having one of these).
