The world is full of containers and service frameworks

Hi,

I have been scanning the web about the current state of different containers.
I used to be a happy phoenix user and was fairly excited about the
ideas around it (and avalon in general).

Now I tried to get an update on this issue and realized that there
are now so many of competing implementations and specifications
(phoenix (not active), merlin (not very mature), Loom (seems like
continuation of phoenix & pico), spring, hivemind...)

Is there a document that would analyze the differences and
ideologies behind all these different containers/service frameworks?
If not could someone at least comment on the differences between
loom & merlin.
