The problem seems to have to do with the HTTP redirect used on the server. Older versions of zsync did not support redirects at all, but 0.6.1 is supposed to handle this properly.
As a workaround, I did this: $ wget http://releases.ubuntu.co/10.10/ubuntu-10.10-netbook-i386.iso.zsync [...] $ wget --spider http://releases.ubuntu.com/10.10/ubuntu-10.10-netbook-i386.iso Spider mode enabled.
