"now my interest is peaked." Piqued. Unless this is the most interest you've ever given Opera ;) Going open source would be cool, but given the nature of the comment on that page, my money's on something like an embedded webserver, with some interesting means of finding and sharing things with it. Maybe some integration with Opera Link, so users can always find one of your running clients (or even Opera in --server mode somewhere on 24/7; something their good cross-platform support will help). Opera do have a very good full text search engine, currently used for email and to index the content on every page you visit, and obviously has the ability to easily generate HTML from content it has stored and indexed; if they wanted to go this route they could easily make some sort of CMS using it. They also do blogs on my.opera. Maybe an integrated blogging engine, which can serve content on its own and also upload it to services using some open protocol anyone can implement (e.g. pushing people to support importing .atom feeds). Publish content on your browser, push it to any online service which supports it, and keep it locally accessible and indexable and outside the control of any third party.
