Feedback needed - Nagios from a smartphone?

I’m hoping to get some feedback from some experienced sysadmins that have Nagios deployed.

We have a product, Rove Mobile Admin, that mobilizes Nagios to smartphones, allowing sysadmins to interact with Nagios from anywhere, and we’re always looking to refine it.

What sort of Nagios features do you feel would be useful if they were available through your BlackBerry, iPhone, Windows Mobile or Android smartphone? DM me or respond back to this topic. In other words, if you could access Nagios from the grocery store when you’re on call, what would you want to have access to?
