Hey, does anyone know of a good tool for PDF annotation on a web page (IE-only is fine, so probably an Active-X)? I'm researching this for a current project and would appreciate gleaning any knowledge you have on the subject. Of course, the Active-X does not have to be FoxPro-specific, since it can be served up to the web page from anywhere (Web Connection, ASP, ASP.NET, static link, whatever), but it does have to be capable of taking an input stream from a URL and saving back out somehow as a changed PDF (not on the local machine, but somewhere back on the web server).

Also, how about good links for PDF Annotation format, etc, from a technical point of view?
