Writing a DLNA server (DMS) in Cocoa/Objective-C/C

Question

I'd like to write a DLNA server in Cocoa for the Mac. Are there any libraries for speaking UPnP/DLNA in Objective-C or C? Failing that, where is the spec for DLNA so I can write my own?

Answer 1

How about this one:

Answer 2

Have a look at Platinum UPnP. It's written in C++, but is very portable.
