Did you read my last question about allowing more than 1 processes to
Does it make any sense at all for my case?
If that was possible i would have
/dev/bktr1stCam -> /dev/bktr0,
/dev/bktr2ndCam -> /dev/bktr0,
/dev/bktr3rdCam -> /dev/bktr0,
/dev/bktr4thCam -> /dev/bktr0,
so that zoneminder would run 4 instances of zmc,
which i can deal with, and effectively solve my problem,
(although not in a fancy way).
What do you say?
