Hi Jens,

This is not an answer to your very, very excellent question but a 
tangent which might shed some light on a future feature.

I think, with some sensors in some situations, there is an option of 
having the user interact with the client (user agent) to assist in 
improving accuracy. This is a feature in the application "Swiss Peaks" 
which has been released by a group in Information Management at the ETH 
Zurich on Android and iPhone. http://peaks-app.ch/

They also have a Layar layer.

I'm aware of the fact that there are many of these Peak finder apps out 
now but the point I want to make is simply that there is an option in 
the application where the user can touch and drag the summit right or 
left to help with the geo-positioning when the GPS is "off".

Is this common place?

If there are registration problems with other sensors, can there be a 
user option to make a manual adjustment? the really, really compelling 
feature would be for the client application to then bring some 
information back to the AR meta data so that, in effect, crowds help the 
information to become more accurate over time (this is not the case with 
the GPS and peaks example, since, presumably the peaks don't move a 
great deal, but could be valuable for some interior navigation or other 
AR visual overlay applications).
