In your presentation you say that serial devices on the Mac are in /dev  
with "no other information".  That is totally not true, unless you say  
"no other information available from POSIX"  ;)  You can get at any  
metadata you want to know about any hardware device in the system (and  
plug/unplug notifications) from IOKit.  The code to do the serial port  
enumeration is rather trivial (as trivial as refcounted C goes,  
anyway):

SerialPortSample.html

I don't think anyone has wrapped IOKit, but it wouldn't be that hard to  
wrap the useful parts.  Maybe I'll look into it, since I do use IOKit  
for FireWire and USB notifications in one of my apps.  My current  
implementation does this with an Objective-C class compiled as a Python  
extension, so from PyObjC I can just objc.lookUpClass and talk to it  
without writing any additional ugly wrapper code.
