Now, first thing, I've tried this a while back with older versions of
apache and php and couldn't get success :(

it should be a rather simple task as long as the proper request and
response headers are sent back.

very first thing you want to send if the request if sufficient enough to
be a range request:
header('HTTP/1.0 206 Partial Content');


See RFC2616 10.2.7 for the response headers needed.
