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.

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.
