You might be able to use something like:
   curl -o <somefile> --time-cond <somefile> -C -
every few seconds or so.

Provided the server supports this, it should respond by
either sending the new content, or with a 304 "Not Modified"
response. (Or possibly a 416, if the file has actually been
truncated since the last request.)
