That seems right, although I'd say just creating your own KStartupInfo copy
with more or less empty bodies should do as well. Just do nothing and always

Probably not, because this is not about the IPC but about the whole
mechanism. Does MacOS X (or Windows) have any concept of launch feedback or
focus stealing prevention? I.e. if you e.g. launch a new app and continue
working with another one that's already open, does the new one interrupt that
when it's ready or does the system prevent that like in KDE/X11?
If there's nothing like that, you don't need at this at all. If there is (and
I'm quite sure there is at least in Windows), you need to find out how it
works. More precisely, if there's any API to control that or if it manages to
handle things on its own somehow. In the latter case again you don't have
much to do (although then I wonder what will happen in more complicated cases
where I haven't found any automatic way in KDE, and I tried quite hard). In
the case of any API for this, you need to map the functionality.

Tracking of the state should be only done by desktop components like kwin or
kdesktop, you shouldn't need to care about that. Normal apps should just send
info to these desktop components.
PS: You might also want to have a look at
kdelibs/kdecore/README.kstartupinfo, which is pretty outdated by now, but the
principle is still the same, if it helps.
