RxTCP6? Re: [OpenAFS-devel] ipv6 support in AFS protcols?

[Troy Benjegerdes]

So, has anyone seriously estimated the cost and timeframe to get a
production version of RxTCP6 up and running? This seems like a
project to put on kickstarter.com or some other site like that,
and start collecting money.

(And can we roll RxK5/RxSSL encryption in if it's not already
fully baked in somewhere? )

Let me also propose something else which is probably disgusting
and wrong, but I want to hear someone else comment ;)

What if, instead of changing all the RPC's, we continue to use
a 32 bit field, and use some flag to identify RxV6, and then
use 24-30 bits of what used to be an IP address as an index
and/or key for a key->IPv6 address mapping structure. Some
of the address space would be for dynamic mappings, while
others would be IDs for a new PTserver/Ubik name to IPv6
address mapping... I'll volunteer to write/debug/hack a 
DNS server that uses this Ubik database ;)

The challenge in changing the world is not in having great ideas, it's in
having stupid simple ideas, as those are the ones that cause change.

Intellectual property is one of those great complicated ideas that
intellectuals like to intellectualize over, lawyers like to bill too
much over, and engineers like to overengineer. Meanwhile, it's the
stupid simple ideas underfoot that create wealth.   -- Troy, Mar 2010
