[dwmw2 at i7 activesyncd]$ ssh fe80::21d:7dff:fe04:dbe2%eth0

wget fails though:
[dwmw2 at i7 activesyncd]$ wget 'http://[fe80::21d:7dff:fe04:dbe2%eth0]/'
http://[fe80::21d:7dff:fe04:dbe2%eth0]/: Invalid IPv6 numeric address.

And curl is just broken for numeric IPv6 addresses completely:

[dwmw2 at i7 activesyncd]$ curl http://[2001:8b0:10b:1:21d:7dff:fe04:dbe2]/
curl: (3) [globbing] error: bad range specification after pos 9

I think you get a little further if you put the addresses in /etc/hosts.
