Re: redmatrix and diaspora federation - we're a bit more than 1/3 of the way there after about a week of solid effort. We might be able to run some limited testing in the next week or two.
Just remember that the last 10% takes 90% of the time.
Also, friendica/redmatrix federation is a bit further down the road, but we should be able to communicate through the Diaspora channel (at least those friendica sites with valid certs; the others are out of luck I'm afraid).
Importing RSS feeds is almost there today. That's just waiting on a discovery wrapper. It will probably land about the same time as diaspora.
[I told you there was method to my madness.]
