I have a working open-source (alpha) implementation of Activity
Pingback at: http://pingback.converspace.com/

and I'm currently working on a proof of concept of activityweb.org,
specifically around "like" and should have something to demo in about
a weeks time.

There are some interesting problems with federated likes (or any
activity for that matter). For example, unlike centralized likes, its
hard to ensure accuracy of like counts since the activities are taking
place on different websites and any problems during the activity
pingback process could mean loss of info.  To mitigate this, an
activity pingback endpoint will need to implement queuing of
unsuccessful activity pingbacks and retry with an exponential delay
(like you typically would do with webhooks). Endpoints could delegate
this responsibility to open proxies (soon to be implemented at
pingback.converspace.com) to simply their own implementation (this is
the equivalent of a hub in PubSubHubbub).

I would love to get feedback and suggestions from people on this list
on how this could be improved upon.
