Iview OSX app?

Looking for a way to watch iView (SBS OnDemand would be nice too) on an old white iMac running Lion.

The iMac is used as a HTPC without a keyboard and mouse (using Apple remote) almost exclusively for PLEX.

Any suggestions beyond screen sharing to launch a browser, which is not a feasible option as it is not simple enough a workflow fir all users??

Browser is the only option for both as far as I know,.

I’m thinking you could use something like RemoteBuddy (a great piece of software!) to launch Safari in full-screen mode, and use the Apple Remote as a virtual mouse?
