[Dnsmasq-discuss] dynamic file generation for dnsmasq-tftp?

Hi list,

Im brooding over the problem, that dnsmasq should send via tftp a file
which would be generated at aquisition-time.

I.e. if a tftp-request comes to dnsmasq, normally the tftp-part takes
the named file and send it to the clent.

If I now have a file, which consists of i.e. four parts, where one part
is generated dynamicly, so that i could send it via p1,p2,p3,pdynamic,p4
at which the first three parts are really big (> 300MB), the rest is
relativly small (<10MB), so copying together takes really a lot of time
and space.

Is there a possibility to send such a thing via dnsmasq-tftp in a
dynamic way? Maybe there is a generic possibility in linux like named
pipes or binary overlay, but Im in the dark at the moment.

Any ideas?
