[Live-demo] Hot Swapping Datasets

I'm very wary of anything to do with hot-swapping datasets.

One of the main pillar stones of OSGeo-Live is quality, which is 
achieved by systematic testing, re-testing, then testing again, year 
after year. We now have years and years of testing of applications 
behind us.

Hot swapping a base dataset invalidates the testing for all applications 
which use that dataset, and consequently is highly likely to introduce 
errors - something we are strong wishing to avoid.

Yes, I agree that it is really nice to make use of a local dataset, and 
someone may wish to do so for one specific example for one specific 
application, which you test yourself. But I strongly urge you not to 
change a dataset for all applications as you either compromise the 
quality of OSGeo-Live, or you are up for many man months worth of 
testing and issue resolution.
