Last night I mentioned that our servers run Open Wall Linux. This morning I saw this blog post from our System Administrator, my partner and Identity Expert Fen Labalme. Here is more information on OWL.
And while I am posting, Fen recently posted this about OpenID.

OpenID, I-name, I-number and yet another alphabet soup
Today, I discovered a new buzzword/alphabet soup that I was blissfully ignorant of.
OpenID: http://openid.net/
Wikipedia: http://en.wikipedia.org/wiki/OpenID
which lead to these:
I-name: http://en.wikipedia.org/wiki/I-name
I-number: http://en.wikipedia.org/wiki/I-number
I-broker: http://en.wikipedia.org/wiki/I-broker
XRI: http://en.wikipedia.org/wiki/Extensible_Resource_Identifier
XDI (XRI Data Interchange) : http://en.wikipedia.org/wiki/XDI
XDI.ORG: http://www.xdi.org/
Data web: http://en.wikipedia.org/wiki/Dataweb
Link contract: http://en.wikipedia.org/wiki/Link_contract
Social web with XDI: http://journal.planetwork.net/article.php?lab=reed0704
Wikipedia - OpenID identifiers:
-- Starting with OpenID Authentication 2.0 (and some 1.1 implementations), there are two types of identifiers that can be used with OpenID: URLs and XRIs.
URLs
--- There are two ways to obtain an OpenID-enabled URL that can be used to login on all OpenID-enabled websites.
---- 1. To use an existing URL that one's own control (such as one's blog or home page), and if one knows how to edit HTML, one can insert the appropriate OpenID tags in the HTML code following instructions at the OpenID specification.
---- 2. The second option is to register an OpenID identifier with an identity provider. They offer the ability to register a URL (typically a third-level domain) that will automatically be configured with OpenID authentication service.
XRIs
--- XRIs are a new form of Internet identifier designed specifically for cross-domain digital identity. For example, XRIs come in two forms -- i-names and i-numbers -- that are usually registered simultaneously as synonyms. I-names are reassignable (like domain names), while i-numbers are never reassigned. When an XRI i-name is used as an OpenID identifier, it is immediately resolved to the synonymous i-number (the CanonicalID element of the XRDS document). This i-number is the OpenID identifier stored by the relying party. In this way both the user and the relying party are protected from the user's OpenID identity ever being taken over by another party as can happen with a URL based on a reassignable DNS name.
DATAWEBS
Wikipedia:
Dataweb standards follow the precedent of Web standards:
Addressing: URIs --> XRIs
Data Representation: HTML --> XML/XDI
Data Interchange: HTTP --> XDI/HTTP, XDI/SOAP
thedataweb.org:
TheDataWeb brings together under one umbrella demographic, economic, environmental, health, (and more) datasets that are usually separated by geography and/or organization. TheDataWeb is the infrastructure for intelligent browsing and accessing data across the Internet.
Why bother?
Convenience: One email address, one ID/password, one identity
Permanance: Change your internet identities without the need to notify your social network.
Security: secured associations
Social web: you own the association, not the web services
Data access: relate data accross diverse sources
Open Question:
Will OpenID work with registration for web service providers like Yahoo, Google, domain registrars, etc?
