So, you can do *some* of this now. The http-server works. I've made a
really small app with it: https://bitbucket.org/robdaemon/mediaemitter/src
- the goal was to make a simple web client to send to my Chromecast. I
didn't get far, as you can see.

I'll have to leave others to comment on the http server. I know it's
thread-based today, so it has scaling limitations.

You can use DSP (Dylan Server Pages) for templating, which is included in
the http server: https://github.com/dylan-lang/http/tree/master/server/dsp

The SQL abstraction layer is built into the core Open Dylan libraries. See:
https://github.com/dylan-lang/opendylan/tree/master/sources/databases/sql
and http://opendylan.org/documentation/library-reference/sql/index.html

I did work on extending the SQLite library and making a SQL library adapter
for it: https://github.com/dylan-foundry/sqlite-dylan

I'd like to see this go further forward though.
