I can only mention all the time, that that is exactly what streamdev-server 
does, thus allowing multiple concurrent connections. Most SVDRP commands are 
already implemented in that protocol (so that it is not necessary to have two 
connections to control streaming and timers etc. at the same time). It is 
guaranteed that multiple commands from multiple clients are NOT executed 
concurrently.

Feel free to use that interface, to add missing SVDRP commands (simply copy 
the code from svdrp.c to connectionVTP.c and add the WRAPPER macros like in 
the other commands copied from svdrp.c), or even use this code as an 
inspiraton for a VDR patch (but give me the possibility to add commands from 
within a plugin, then) :-).
