The general consensus is that *displaying* data (POIs, etc) on top of a OSM 
layer is not a derivative work, so the ODbL doesn't apply to that data. Just 
remember to mention attribution and where does each layer come from in your 
app's documentation.

If you're keeping data apart, it'll be perfectly fine. Being able to switch 
OSM on and off would be very good. However, if you're mixing OSM POIs with 
some other POIs with no easy way to tell them apart, then ODbL would apply.


I hope that clears it up a bit.

Best,
