He could just open a new form with browser control in it, and have a report-web-preview inside the app. And open a new instance of this form for every page - or a new tab on that form, whichever suits him better. So the user doesn't leave the app, which I figure creates fewer focus problems.

Well, it's an option - and may give him more control over the browser. ShellExecute() just spawns a process, where you can only pass a few parameters and then it's gone beyond your reach, more or less. Browser control is, well, controllable :).
