Could we use something better than zip for the dmd package?

Enthusiasts have created portable open-source software emulators
for many old platforms. Hell, you can boot Linux (and UNIX V6
on a PDP-11, for the other side of the spectrum) in your web
browser these days!
I would say that today's hardware architectures (and those from
the past two decades) have acquired enough mass that they'll be
accessible for the foreseeable future (our lifespans), mainly
thanks to open-source emulators. The main problem is with
copyrighted software: you can't buy a new copy of Windows 95, but
you can't download it legally either.
Of course, storage media is a different matter.

Indeed, proprietary file formats are the bane of archival. It
doesn't seem to stop other software from importing data from
them, though. Didn't Thunderbird have a feature to import data
from Outlook Express?
Even using open-source software that stores data in simple
formats may not be very futureproof. Future versions of
Thunderbird may convert the data to another format, without even
notifying the user (after all, the great majority of users don't
care about such things). Remaining on an old version is risky due
to discovered security vulnerabilities.
