ePortfolio Apps Needed?

Today, I received the following email message from a graduate student in the UK:

I am very interested in the mobile application development we have discussed and intend to make it the focus of my research.
I will be developing for the iPad, iPod, iPhone platform initially.

Just a thought, do you think the greatest need currently is for apps which connect to an ePortfolio such as: Wordpress, Blogger, Google Docs or similar, to enable uploading, editing and reflection of digital content? 
Or, is there also a need for a standalone mobile ePortfolio app?

Here is my response:

There are many purposes for ePortfolios, that require different types of tools (learning/reflection, showcase/employment, assessment/accountability). There are also many portfolio processes to be supported by different tools: creating/authoring digital content, collecting my work, reflecting on that work, selecting (hyperlinking or embedding) that work into my presentation portfolio, writing goals, presenting my work, getting feedback, etc.

With Web 2.0, an ePortfolio is really an aggregator of my work that is stored at many places online: video in video sharing sites like YouTube, Vimeo, blip.tv, etc.; images in Flickr, Picasa; documents in GoogleDocs, scribd.com, or lots of other locations; audio in Myna, etc. What we lack is an aggregator. We need a database to keep track of our online content, sort of like a database that we can use to organize our personal content, wherever it resides on the web. If you look at the report that was written by Ian Fox in NZ, a database of personal/academic content, that can be meta-tagged, is the missing link.

I imagine something that acts like my Macintosh in Garage Band or iMovie or Keynote, where I pull up Media, and it shows me my photos in iPhoto, my movies, my iTunes files, etc. I can select that piece of content and insert it into my document. We need a Web 2.0 equivalent, so that I can get to my content wherever it is stored online. What I need is not to insert the actual content, but to be presented with a choice of a hyperlink or an embed code that I can copy and paste into whatever presentation portfolio I am using. Right now, I have to do this task manually, link by link. For me, that is the need: a content management system for Cloud content, that is accessible on a website using any browser or mobile app. We can upload all kinds of data to the Web from our mobile devices... how do we organize all of this content?

Above is a diagram of eportfolio components as described in BECTA and JISC reports, and you will see where there is a need to organize the Digital Repository: online space to store resources and an archive of evidence.  I have also defined the Two Faces of ePortfolios, which are the workspace (reflection + archive/collection) and showcase (presentation+feedback). Most of the commercial tools organize the showcase... no one independently organizes the workspace right now (except what I do on my own in my blog or in a spreadsheet/matrix). And it needs to be easy enough for a 3rd grader to use! Maybe I'm thinking about a version of the MyLifeBits research that Microsoft conducted around "life store" of data.

So, we'd love some input: what type of apps are needed to support ePortfolio development using mobile devices with access to the Internet?
