I've been considering releasing (as a patch) a separate nagware version
of Ion, which would have a license without the 28-day clause. The patch
is included as a draft (without any accompanied permission yet to treat
it as an insignificant change). Presently it checks the latest release
redirection [1] every 28 days. An annoying call-home feature, I know,
which would not be featured in the standard release (including my
ZeroInstall feed). As is apparent from the README changes, the patch
requires luacurl [2]. Discuss it if you want. I however doubt that the
unconstructive distros motivated by ideology and maintaining their own
power, would accept even that, although the resulting license should be
"free" (and would be GPLv3 compatible, if based on it intead of LGPLv2.1).
And yet, the package management system is the right place for this kind
of features, not programs themselves (reinventing a half-assed package
management system).
