I have managed to add this blog as a subscriber to my identi.ca account. This means that I can post directly from Identi.ca (or any other application that supports OpenMicroBlogging (OMB) protocol, such as Laconi.ca) to my blog.
To achieve this I wrote a plugin that uses the power of XRDS-Simple plugin to generate Yadis document which specifies the location of OAuth and postNotice, as required by OMB (see konstruktors.com/blog/?xrds). A modified version of WP-OAuth plugin takes care of OAuth 1.0 dance (for the initial authorization and all the update notices) and adds support for receiving updates from the listenee (any Laconi.ca application on your phone, for example).
Why This is Unique
It allows posting directly to your blog from any of the laconi.ca (twitter like) applications, and these updates are pushed to your blog in real time, just as if your blog was one of the laconi.ca users subscribed to your updates.
This could be very useful for live blogging. You could use all the tools which can now post to Laconi.ca — SMS, Jabber/Gtalk, e-mail and various desktop and mobile apps — to publish on your blog.
And with OBM everything happens (almost) instantaneously as opposed to RSS which has to be polled.
