These are actually vastly different pieces of software, at least from the
description, and a first read of the code.  My understanding is the
software you linked to here basically takes the DNS work out of lookups for
people, as we released: https://github.com/netkicorp/wns-api-server  Its
our Wallet Name Lookup server.

Addressimo, as I described above, provides a different purpose.  Its a way
for service providers, mobile wallet providers or end users to have an
online server that can serve unique wallet addresses ala HD Wallets (BIP32)
or signed Payment Requests (BIP0070).  This allows for an easy way to
increase security and privacy by serving a unique address for every
request, and/or sign the address (and other optional data) with an X509
private key to prove ownership of the address in a way independent of and
supplemental to the DNSSEC chain (also can be DANE for yet another layer of
security).  It also supports offline signing of the Payment Requests so the
server doesn't have to have access to a private key, or need to be trusted.

I'm a little confused by these closing statements.  Our system has, from
the beginning been open in terms of the fact that anyone could both serve
names or do lookups without ever touching our servers, talking to us, or us
even knowing that they did it or that they even exist.  Our system has
NEVER been one where folks were required to use us for any portion of the
service, and from our first beta product launch our open source tools did
all lookups against DNS records and the blockchain, never any proprietary
servers or interfaces on our side.

In terms of the format itself being open, we have already made several
extensions and modifications to it as a result of conversations with
industry participants in order to ensure that what we are building meets
the needs of the community at large.  We will gladly continue to do so, it
is how we ensure we are building something everyone needs!

I'd love to know where you got information that we were in some way a
closed and centralized system so that we can have an opportunity to clarify
that misconception.

In terms of finding a common standard, as I said, I am thrilled to have the
conversations, but there are some places, highlighted above, that would
cause me to hesitate to "just implement" the Open Alias standard.  I can
also see places where bringing the formats together to one standard could
have strong benefits, for example:

I think formatting the record as a key value pair with versioning has
merit, and would love to move it in to what we are doing (and likely will).

On the other side, I think the two level lookup provides a lot of value at
scale over trying to send back a bunch of text records when only a small
portion of the data is used.

I'd love to hear thoughts from others in the community on mandating DNSSEC
and thoughts on DNSCrypt.  I have a strong opinion on both of those but
would love to engage in thoughtful dialogue around what path best suits the
need of the community.

Looking forward to the discussion!
