"may be", unfortunately it's NOT! CUPS purges ANY jobs to a 
self-implemented backend if:
    * the job goes to another host
    * -o raw is used
    * the job is not postscritpt.
In other words: if my own backend should work, the job file must be 
postscript and the backend must be located on local machine and -o raw 
must not be used. See thread "no data arrives to /usr/lib/cups/myBackend 
(0 bytes)"!   I n c r e d i b l e !
