This has been asked on the forums and I have also promised on the umbraco site to release my multimedia indexing hack. The code is live with one site www.synexus.com and is going to go live with another site soon. Its a hack of the umbracoUtilities package that Niels originally wrote. I have also got some code written by Niels that is work in progress for multimedia indexing. Download the zip read the readme and off you go. Any questions comments post them here.
One thing I forgot to mention in the readme.txt is to copy over the umbSearchResult.ascx to usercontrols/umbracoUtilities you can find a copy of the control in the src directory of the zip.
Ps apologies for the size of the download there are some big pdf handling dlls there!
