Let's see if I'm understanding things correctly...
The NSNetService publishes on a port and the server creates an
NSFileHandle (fh1) for the NSNetService to begin listening to
connection attempts. This fileHandle is listening on the same port on
which the netService was published.
An NSNetServiceBrowser on the client finds the NSNetService and
notifies via its netServiceBrowser:didFindService:moreComing: delegate
method.
The client attempts to resolveWithTimeout to the netService.
If the resolving succeeds, then the client attempts to connect to the
server by creating an NSFileHandle init'd with a fileDescriptor
gleaned from the [netService addresses]; This now opens a port on the
client.
(This is where things start getting fuzzy)
The server, meanwhile, is notified that someone is trying to hook up
to fh1, and gets a new fileHandle via the notification object sent
along in the NSFileHandleConnectionAcceptedNotification.
Is this new fileHandle different from the original fileHandle on the
server? Is this new fileHandle operating on a different port than the
original? Is this even the proper way to be going about this? Am I
anywhere close to getting this working?
Thanks a ton!

How does one go about advertising a service via bonjour like in the
Picture Sharing example AND allow multiple connections instead of
just one? Is it as simple as creating multiple listeningSockets? Or
create a new listening socket each time you get a connection to the
existing one?
Reading a tutorial on network programming may prove helpful here.
Here's one:

The short answer is that a single listening socket is sufficient; a
new socket representing a connection is created when each client
connects.
