Yes but when they don't each have a tool like a DB layer it means
borrowing pieces from other software to fill the gap. Very hard to
keep track of and troubleshoot when upgrading.

Yes but unlike Apache Yaws provides an application layer
(yapps,appmods,yaws pages...) but nothing to connect to a RDBMS.

If you are starting a project from scratch and only using Erlang then
this is okay. But I think the reality is most will be migrating from
another technology or data source.
I am saying this only because I strongly feel that adoption of Erlang
and starting community growth is in making the transition as easy as
possible from other technologies.
Just think about how many would choose Nitrogen over Rails (like me)
if they did not have to worry about re-designing the database. Many
CMS and other web application might be built on Nitrogen if the web
developer only had to connect to a blog or wiki mysql db and start
building from there.
I hope you guys decide to implement something because it would bring a
breakthrough in interest in using Erlang and your framework.
