So, break out your H&S or your wallet :)

How about adding an option to atftpd to enable "check the execute bit" on 
the requested file. If the file has the execute bit, set the MAC, IP 
Address, etc. as environment variables, exec the file, and return the 
output to the requester?

Then, you could write (for example) spa841.cfg as a shell script which 
have access to the MAC, etc. and could run sed/replace/preprocessor/m4 and 
create the "file" on the fly.
