I've used "Cool Edit" to do exactly this, when I was actively involved in Production work at WFIF. :) I did, however, find a method where the find/remove silence *DID* result in not only a usable product, but a natural-sounding one. :) Finding any silence longer than 750ms, and limiting them to 750ms seemed to be the "sweet spot". ;) It worked VERY well at reducing 31 minute files to the necessary 28 minutes. :)

It took a bunch of trial & error with MANY do/undo cycles to come up with that 750ms setting... but I share it willingly and gladly. :)

As for scanning for dropped moments in LONG recordings... Cool Edit (Adobe Audition) will do that nicely, with the right parameters.

Adobe Audition 5.0 has a built in find silence feature.  I used to use it to edit our pastors 45 minute sermon down to 30 minutes.  After removing all the none essentials and still finding the sermon to long, I use the find silence feature to shorten the pauses in his delivery.  By the way, find and remove silence in this scenario does not return a usable product!

The feature allows for customized levels for 'silence detection' and 'audio restored'.  It would also allow for the replacement of a given length (or longer) of silence with a a predetermined length of silence, and then leave a marker in the file in all the locations where the function had been executed.
