connect ... so the database itself runs indepently (and has a
comunication channel to a certain amount of clients)

so, in your example its not even embedded or extended that we're talking
of but connecting; well, it is no secret that luatex provides sockets so
you can start a luatex session, connect to it, send some text, and get
back whatever you want, in the sense that you can serialize for instance
a node list, (which in itself is not that useful as it lacks resources)
anyhow, this is exactly what arthur also mentioned so ...
