[SunRay-Users] Customizing firmware for SunRay DTUs?

we are currently in the process of redesigning our SunRay infrastructure and 
need to switch from a dedicated interconnect setup to a "remote shared 
subnet" setup for technical and administrative reasons. In the new setup we 
will neither have control over the DHCP parameters provided to the DTUs nor 
the DNS name space so we cannot easily configure the list of SunRay and 
firmware servers for the DTUs.

Deploying the "GUI firmware" and configuring each DTU manually works fine but 
isn't really an option for 250+ terminals. Apart from that it really seems 
attractive to not have a settings menu where a user might (accidentally or 
intentionally) misconfigure the device.

It would be really nice if there were some kind of mechanism that allows us to 
generate a custom firmware that either

- contains a fixed list of (names or addresses) of SunRay and/or firmware
  servers to contact, or

- issues DNS queries for the full qualified names sunray-servers.my.domain
  and/or sunray-config-server.my.domain.

Equipped with such a firmware, the DTUs spread across the campus would be 
really "zero-admin" devices for us.

So the question is: does anyone know if it is possible to get/buy such a 
toolset that allows to create a custom firmware? Of course other hints to 
achieve the same result are welcome as well... :-)
