Would you care to elaborate on "to be necessary to make a modification 
to the TFTP protocol" part ?

The basic TFTP protocol allows for a GET and PUT file operation.  My 
vision of how it might work uses those operations if the file name is 
earmarked at the server as a CGI the server sends data to the executable 
or reads data from the executable.  A basic pipe mechanism would do the 
trick, otherwise a run executable using a temporary file.

Simple is good.
