There seems to be lack of examples using LLRPC, but could that mechanism
be used? That is in element x

     Element *e; // Other element

     e->llrpc(MY_SETKEYCOMMAD, &keydata);

What puzzles me that all LLRPC commands seems to be in llrpc.h? I would
have expected each element itself to define the commands it understands
in the own header? Would I have to allocate command values as globally
unique, and not just element specific integers starting from 0 or 1?
