I believe I know what is a daemon in computing, but what is a headless daemon? Besides bitcoind what other examples of headless daemons that are both clients and daemons we have in mass use currently?

There are several different types of Bitcoin clients. Header-only clients like MultiBit trust that the majority of mining power is honest for the purposes of enforcing network rules such as the 21 million BTC limit. Full clients do not trust miners in this way.

A daemon is a program that runs in the background usually without direct user interaction. In the windows world this is called a service.
(http://en.wikipedia.org/wiki/Daemon_%28computer_software%29)

From http://en.wikipedia.org/wiki/Headless_system:
A headless system is a computer system or device that has been configured to operate without a monitor (the missing "head"), keyboard and mouse (KVM). A headless system is typically controlled via a network connection, although some headless system devices require a connection to be made via RS232 for administration of the device.

A headless programs is one that can run on such a machine.

So joined together a headless daemon is a process running in the background not requiring any KVM resources.

Oh and before I forget, virtually all unix daemons can be run headless. So, for example your mysql server can be counted as one (I prefer postgres if I really have to make a choice for a SQL backend, but I reckon mysql is more widely known outside the geekosphere).
