I like the "Half time. Play will resume at ..." message. I meant to suggest something like that a while ago. :)
One problem, though. When I reload the matchviewer during halftime, the "play will resume at ..." message displays a different time. It looks like it just adds 10 minutes to the time (my computer's time, not the time of daythat BB displays in the browser) at which I reload the viewer. (Makes sense if I watch the whole game without reloading between halves, of course.)
