Search within attachments

Request feature to search within file attachments to allow for creation of comprehensive document management system. There is already a Drupal mod called search_attachments (http://drupal.org/project/search_attachments) that purports to add this capability however it has not been released:

"The search_attachments.module appends the text extracted from attachments to their parent node's search_dataset database table so that the node text and the attachments' text are treated as a single document in Drupal's search engine. In order to extract the text from attached files, the module calls 'helper apps'. Popular helper apps for *nix include cat (for plain text), catdoc (for MS Word files), and pdftotext (for PDF files). Search_attachments itself will work on Windows servers but the current lack of command-line helper apps for that platform restricts the usefulness of the module outside of the *nix environment."

Could this capability be added to Web File Manager?
