You can run 'ifconfig' without being root, so there must be a way. At
very worst, parse ifconfig's output.

The way you talk of "the" external interface, I'm assuming this
computer has only one. Is there a reason for not simply binding to
INADDR_ANY aka 0.0.0.0? Do you specifically need to *not* bind to
127.0.0.1?
