I realize that the last spin came out as recently as March 2013, but considering the volume of updates, thanks in particular to the switch to Jessie base (Debian 7), wouldn't it make sense to release a live/installable ISO, which can then be easily copied and swapped around. In many parts of the world the sneakernet still serves a major purpose.
Also, despite being a semi-rolling distro, there are many cases where having fresh installation media available locally is useful or even necessary.Is an ISO refresh being planned?
And finally a somewhat unrelated thought: Why isn't LMDE listed by Distrowatch? The chart-leading Mint entry only details the buntu-based releases, although new LMDE ISO releases do get mentioned under the other Linux Mint title.
