The solution, as Bill mentioned is to instantiate your application over
every possible native datatype and choose at runtime, which instantiation to
use. We do this in our applications here . As an example, see VolViewPlugins
in InsightApplication (
http://www.itk.org/cgi-bin/viewcvs.cgi/VolviewPlugIns/vvITKMask.cxx?rev=1.2&root=InsightApplications&view=log)
As Bill mentioned, you can get the type you wish to use at runtime after
ReadImageInformation and then instantiate the readers..

Doing so does increase your compile time 10 fold, cause you're compiling
every parametrization of the template now :-(.....
