Eric,

I think the --config option takes effect after registration which is likely
why it is having no effect.  Setting GDAL_SKIP ahead of time as an
environment variable, or building without JasPer should ensure GDAL
uses the JP2ECW driver instead of the JPEG2000 driver.

1:10 expansion is common, 1:100 less so.  Note that TIFF only supports up to
4GB files, so if it is going to be very large you will need to use
a different format, like HFA (erdas imagine).
