I would recommend against doing that. Use a hash instead, something like this:

    $paths{megatron}{ftp}  = "/foo/megatron/ftp";
    $paths{megatron}{http} = "/foo/megatron/http";

Does that make sense? You're much better off using a multi-dimensional hash like this, rather than using symbolic references (which is what you'd be doing).
