Well, given there are already some existing hardware devices based on 
VLC, anything that VLC can handle could be handled in such devices (OK, 
they are used for streams, not CD/DVD/HD reading). We are trying to 
motivate some devs to make USF work with VLC, as DShow seemed too 
complex for the moment. It hope it works...

Yes, MP4's ttxt should be supported too someday in Matroska.

Vobsub is obviously a candidate for these profiles, as they are already 
handled by the DVDs. SRT and other processed text might not. Because you 
need for CPU for that. Probably why DivX chose a picture based format...
