I’d like to self-host everything, and then broadcast those materials out to the relevant locations (rather than vice versa). With that in mind, these are my wish list services I want to replicate in a self-host+broadcast method:

• Status Updates — broadcast automagically to Twitter, Facebook, Tumblr, and Google+, including long-form article notification
• Gallery (media management) — with broadcasting to 500px and flickr.
• Bookmarking — with broadcasting to delicious and google bookmarks
• Identity management — tracking what services I’m connected to, with notes as to which are broadcast TO, and which are still broadcast FROM (plus aggregation of all these services into one self-hosted spot wherever possible)
