Thanks Gregg,

Things would have been a lot different for Jini with IPv6 networks.  It may have been the
succees that Sun originally envisaged.

The majority of issues new users experience relate to underlying network setup.  IPv6 pretty
much addresses network autoconfiguration, plays well with multicast and doesn't require port
mapping / network address translation.  It breaks the server - client, publisher consumer
model of todays web and allows true peer to peer networking and dynamic discovery on a global
scale.  Yet ironically River doesn't support IPv6 multicast discovery.

River has a lot of strong points for Java developers, it has flexible configuration and various
communication transport options.

We are on the cusp of our next release and a major network evolution event.  Somehow we need
to figure out how to increase developer participation.  There's plenty to be done.

Subject: Re: IoT

The maximum number of devices that can be on the internet with IPV4 is equal to the maximum number of IPV4 unique public addresses times the number of ports available for TCP at 65535 and UDP at 65535.  Basically, quadrillions if there was a single protocol ever active on each device.  Some of the bits in the IPV4 header protocol field could be used as multipliers for another few quadrillions more.  I’m still surprised that there is not visible, if not wide spread use of the protocol bits as network multipliers.  Perhaps there are in some places in the world.

There are lots of IPV4 possibilities.  But, there are limitations obviously.  I’ve been hoping for ipv6 for a decade and it should of happened two decades ago...
