#3This sounds like awesome news!
- How it compares to Cassandra regarding latency? - How is the client API? Does it support lock free communication? Can you send things to nodes in batches?

Latency is great - http://www.scylladb.com/technology/cassandra-vs-scylla-laten... and we promise to improve it further.
The client API is CQL. We have thrift too but it's not mature enough. We'll invest in thrift per community feedback

We target http://www.scylladb.com/technology/cassandra-vs-scylla-laten...
DB API (CQL) is Cassandra compatible, so clients does not have to change.
For more on the lock free communication see http://www.seastar-project.org/ Seastar is the underline framework of Scylla
There is an open bug for batch https://github.com/scylladb/scylla/issues/332 hopefully we will fix it shortly.

#6The server is AGPL 3: http://www.scylladb.com/opensource/
Client libraries ("drivers") Apache 2.0.
This is fine, but it really should be on the front page.
