When you do ogg123 < file, the shell sets it up so stdin is the file, and is
seekable, but when you do cat file | ogg123, stdin is a pipe which isn't
seekable.  So the problem is that ogg123 apparently can't read from
unseekable files.  The codec allows it, but ogg123 apparently can't do it.
(And it should.)

That said, you just set up the remote box as a fileserver, or if you need
streaming, try something like IceCast or Video LAN Client.
