As far as i can see GNU screen just creates the fifos in /var/run/screen/*/*
if you have multiple session running you have to specify the session
with -S. I don't think this is better than the current dvtm behaviour.
Also why use "screen -S session -X cmd" if you could "echo cmd > fifo"?

Anyway the DVTM variable would just be to detect dvtm. So you could
write a shell startup script which contains.

 [ ! -z $DVTM ] && dvtm-startup-script
