Is it possible to redline or comment on PDF files?
Yes, this feature is provided by the full version of Adobe Acrobat. Freehand or vector-based lines and shapes can be combined with typed comments, all of which are readable with the free Reader program. PDF-based redlining is a great way to save time and money on checksets. Design team members can email their PDF files to each other for review and comment, and then pick up changes for the final production drawings without ever printing anything out on paper.
