I was wondering how about using fuse for exposing the nodes to enduser applications? Cuse (Character device in Userspace) which is an extension to fuse also supports ioctl transport with linux. It will probably soon affect our project since we are about to release a FreeBSD driver for USB DVB-C/T/analogTV/FM Radio device soon. http://support.sundtek.com/index.php/topic,4.0.html I have no idea how the other dvb devices work on FreeBSD, our package comes with it's own stack which emulates the existing linux-dvb v0.3/S2-API/video4linux1/2 stack.
