RSS Readers do not care about updates to an existing listed URL, that's how how it works. You need to change the listed URL each time you change the content - and your permalink in particular needs to be unique for each new item you add. A permalink means a link which will always refer to that content - index.html will not always be that content because you will change what's at index.html in the future.

You could work around it by using URL arguments or anchors:

blahblah.foo/index.html?rev=44
blahblah.foo/index.html?rev=45 etc.. or:
blahblah.foo/index.html#rev=44
blahblah.foo/index.html#rev=45

Overall I fear that you aren't using RSS for its intended purpose.
