If she uses Firefox, there's a MediaHint plug-in that works great for accessing iPlayer. She can download it from here, then just drag it into any open Firefox window. She will need to changer her privacy settings to "always use private browsing" otherwise it won't work properly. That's under the History option - change to custom settings and then tick the private browsing option. Of course, how well it streams will depend on her connection, but it does let you access iPlayer.
