Android :: Appwidget With Fast Updating Needed

I would need a fast updating (minimum 5 frames/second) appwidget which can be on the desktop all the time (like the cpu usage or other things mostly measurement gauges).The appwidget is not a "must" but I've found it easy to configure for any customer so the management is easy and I need those gauges to be shown like an appwidget on the desktop.The only problem is the update speed - I've seen that appwidget is not really thought for my needs. In my case it's not about phones, the small unit will always have power supply so draining the battery is not an issue. I could tweak the 30 minute update time but it doesn't helps too much - the appwidget framework is simply too slow with all that serialization and would eat too much CPU. What other solutions can be used? I've seen that a system service (LoadAverageService for example) would do the job but that one is not really configurable, has to be compiled into Android so I kinda don't like it. The same is valid with custom app screens or any other solution which needs an custom Android build. So this is a last solution if nothing else works.

A good solution could be if the Appwidget framework would accept other views than the enlisted ones (AnalogClock, Button, Imageview, etc.) and the update would be done internally in the widget, not through the appwidget serialization chanels.
