think of this as a NetVibes-type identity aggregator or your Google Homepage - where you centralize all your identity info & interactions.

The different sites might want to advertise on this site - since they would be reaching people who have multiple online identities.. and might want to compete for your eyeballs or loyalties..

I am guessing that this is where many startpages (pageflakes, netvibes) are heading. By building "flakes" or modules that update information from those kinds of services, I am guessing they are heading towards this kind of centralization.

The concept is a sound one. I wonder how hard it would be to develop a new project that could overtake existing start-pages.

I think one could write a small program which gives you a way to enter Usernames and passwords into a database. The program will also encrypt the database.

When the user comes to a website, the user will put their cursor in the Username field and execute a keystroke. The program will then detect the domain of the currently loaded webpage, retrieve it from the database, insert into the Username field. Ditto for the password.

This keeps user info on your desktop, rather than a central location which can be hacked, etc. It also allows you to implement this without any "opting in" from the website.

PS: I'd call it KeyChain.

I like it but it's important to be clear what it's about.

The key value here is NOT "remember your passwords" (Roboform does that just fine, thanks).

It's "see it all in one place" and "1 click access to manage your stuff."

Jeb & PsychSplash are on the right page. Codec is not (sorry).

The whole idea of this is to give you an online "startpage" that you can access from anywhere - which will pull & aggregate all your online accounts in one customizable start page.

The analogies of NetVibes and the Google Homepage are sound.

Use Case example: you connect to your "lifepage" [Hey - LifePage - I like that!] and see there are new updates to your CambrianHouse messages, your LinkedIn Connections, your MySpace profile, messages on your Blog, Personal Messages on some bulletinboard/forum, responses to comments on BoingBoing, etc.

With a few clicks - you can check the status of & zoom off to any facet of your entire "Online Life".. all from your online LifePage..

I'm not familiar with all the various products the comments have mentioned (all the stuff with a capital letter, basically!) but:

- I have used a lot of online identities, often just b/c of switching providers as well as signing up to various services, lists, etc.
- I don't necessarily ever want them all in one place, b/c I'm concerned about security
- still, there are some that I would be comfortable having in one place, but I would want to be able to set up more than one account on this service - as silly as that may seem
- I like the feature that says "Hey, there's been some activity in this account" - so I think I understand this product. Instead of me having to type in the url of yahoo and log in, and check my mail, and then the url of cambrianhouse, and log in, and check whatever items I'm watching - the robot would tell me where to go and I could do it in one click.

Yes, I like that.

Sorry, I had to think out loud to figure it out.

How does it make money?

Probably same way Yahoo does - I have free email there & I assume it's being paid for by the ads on the page. (Gee, I wonder if my buying behaviour is even slightly influenced by those ads....)

Giving it an up vote.
