Go for it.
A few particular corner cases to make sure we handle right:
1) IPv6 is supported, but not enabled on the system (no interfaces, not
even loopback, have an IPv6 addr bound to them). I've gotten bit by this on
Solaris (see
http://sunsolve.sun.com/search/document.do?assetkey=1-66-240906-1
for a related example), and Redhat/Fedora boxes.
2) IPv6 is turned up, but the local MTA only binds to 127.0.0.1 and not
to ::1 or ::*.
