The way I see it, the problem isn’t unique for travel records:
I run Google Maps (and have Latitude enabled) on my mobile phone. My location is thus shared with all my other (approved) Google contacts.
However, there is no way for me to share that information with my Facebook account or my Twitter account unless I run additional, other tools.

It applies to my GPS Location (Google Latitude), my latest thoughts (Twitter), my friends (Facebook), my pictures (Flickr), my restaurant reviews (ZAGAT), a list of my books (in Amazon) and a list of my favorite movies (in IMDB), etc.

The solution here is what you refer to as a “bucket”. I would need a digital bucket in which I put my “stuff”: GPS information, recent pictures, my travel itinerary, etc.

Ofcourse, like OpenID, it would be up to me to decide where to “park” my bucket and who I give access to it.
Applications and companies can request access (to read or write) under conditions (approved my be).

I’m probably overreaching here, but I’m trying to make the point that it’s not only the travel industry that needs such a solution.

And: I think it’s a pipedream that any big company would pick this up voluntarily any time soon, since the ‘lock in’ is (in my examples) what allows them to make the tools/services/sites in the first place.

I am just a techie with a vision! [Spells danger that!]

But that is like asking a shopping trolley/basket if it vegetarian. A shopping basket surely doesn’t care what is in it – it is just a container designed for convenience to shop with.

Think of this Cloud super PNR idea as a bucket that data can be put into, can be peeked into, and data removed from. It would be down to the individual what travel services they wish to give permission to access their PNR – hence it would reflect the real world mindset of the traveller.

I like the look of your site but it isn’t quite the same idea (having taken a quick look). But maybe you could do it (but you would have to take a much more of a platform strategy than a site one…. looks like you are going the site one initially?

Traxo currently auto-detects, validates (traveler name match), unlocks, normalizes, de-dups, centralizes, sequences, and intelligently re-assembles (it back into logical ‘trips’) confirmed travel reservation information from over 40 travel sources. Since direct-connects / APIs / web-services don’t yet exist for reservation information we’ve employed the same approach that Mint.com and Yodlee have uses to aggregate financial information. And, as you can imagine, with centralization comes added responsibility, so we’ve spent an incredible amount of time building the appropriate security / privacy / sharing tools directly into our base system.

We just launched our public beta last month. Please take a look at the site. I would love to compare notes and visions for how this service unfolds. Let’s plan to chat later this / next week?

Yes – thats it! [I worried that no one understood what I was getting at]

Would also enable new entrant entrepreneurs to do transactional services (or provide services that interact with a transaction).

That would set off a whole new wave of innovation (currently new entrant entrepreneurs tend to go for social or inspiration / product review type sites – but this would give them something else to innovate with)
