I have one other to add to that - misc shared utilities... I've been doing 
some exploratory work with dvbsak, and I've put "bitstream" in there since 
its nice and generic. I've also extracted the dvbcfg_util string parsing 
stuff and moved it there as well.

I'm going to have a go at seeing how feasible dvbsak really is tonight by 
re-implementing part of the SI code using it.
