No, it is not weird at all. The GPL is not to punish Rene, it is to
give rights to Ed (and everyone else). If he has received a legitimate
copy of ExactScan, he is entitled to the SANE portions. Since
ExactScan comes as a free trial, everyone is a legitimate user. There
seems to be no other way to get this code than asking Rene directly.
ps- these license issues would be clarified by switching to the LGPL,
but because the copyright holder of SANE is each individual author,
you would have to get all of their permission. An impossible task,
"The truth is an offense, but not a sin"
