I implemented IPv6 support in Yxa (an SIP server/stack written in
Erlang) recently. The only problem I had was with the UDP receive
buffer for IPv6 being 1024 bytes (R9C-0) while it was 4 or 8k for IPv4.
Have a look at our source code if you wish,
I haven't tried the Erlang FTP module with IPv6 though - just gen_udp,
gen_tcp and DNS resolving stuff.
PS. IPv6 is still default disabled in Yxa, but that is because we
otherwise risk proxying requests from v4-only to a v6-only user agent
(or vice versa) with the result being that they can't communicate (for
VoIP - send audio) to each other, which would not be appreciated by
