How does NEO compare to RelStorage? NEO appears to implement the
storage roughly in the same way; store pickles in tables in a SQL

Some differences that I can see from reading your email:

* NEO takes care of replication itself; RelStorage pushes that
responsibility to the database used.
* NEO supports MySQL and sqlite, RelStorage MySQL, PostgreSQL and Oracle.
* RelStorage can act as a BlobStorage, NEO can not.

Anything else different? Did you make any performance comparisons
between RelStorage and NEO?
