You could use `sudo lsof -p <unicorn-PID>` to see all the open files of 
a running unicorn.  This will show you shared objects, files, pipes, 
sockets, etc.

Unicorn defaults to listening on TCP 0.0.0.0:8080 unless you tell it 
something else. It wont listen on a unix domain socket unless you 
configure it to.

You can use --listen with the unicorn startup script 
<http://unicorn.bogomips.org/unicorn_1.html> or the 
listen(address,options) method in your unicorn.conf 
<http://unicorn.bogomips.org/Unicorn/Configurator.html> to change this.

I don't see how being a collaborator on a joint effort means you can't 
change config, it just means you need to discuss and agree on the common 
configuration.
