A Splendid Example Of A Renumbering Disaster

It's Friday.  Time to plug IPv6 some more. :-)

http://b.logme.in/2012/11/07/changes-to-hamachi-on-november-19th/

LogMeIn Hamachi is basically a NAT-traversing layer 2 VPN solution.  They 
avoided conflicts with RFC 1918 space by hijacking IPv4 space in 5/8, now 
actively being allocated by LIRs in Europe.  When that didn't work (see link 
above), they moved to 25/8, allocated to the UK MoD.  While I'm almost sure 
that they haven't got it quite so wrong this time, following the comments says 
that the idea was not only a very bad one to start with, it's cost a lot of 
people a lot of grief that IPv6 was clearly going to mitigate in renumbering.  
Perhaps it is why they recommend it per default, if not for the number of 
applications that would be broken by it.

By the way, is this an application that the new shared transition space might 
benefit?
