I am looking for a nice library that can talk to GMail from a Mac application. Really, I am thinking about writing a GMail application for the Mac. Thunderbird and Mail.app just don't cut it for me.
Anyway, the library should be written in C, C++ or Obj-C or at least have interfaces for those languages. Of course, anything free and/or open source would be greatly appreciated.
I think vmime should work for this.
