I found this site and thought it would be cool if the entire bitcoin ecosystem could be managed on one toolbar. http://www.conduit.com/
This could provide links for all the assorted bitcoin sites as well as updating exchange prices and allow searching of every bitcoin site from one box. Everyone who has the toolbar installed could be messaged when a new version is released as well as chat to each other. A download link could be added as well as the ability to launch bitcoin from your toolbar. Mybitcoin could be added or even an address book of favourite bitcoin addresses you collect like sticky notes.
Privacy and anonymizing tools could also be added for the paranoid.
Could someone run a bitcoin exchange using this? A business directory?
I know a lot of people dont like toolbars but the ability to have everything in one place in my browser would be attractive. Conduit also has 170 million users. A bitcoin app could also be created for the marketplace that performed similar functions...a desktop gadget for instance.
