Well, it's there and you can use it. But you can't expect much 
portability and flexibility.

Because it's portable, you can use more colors, and you can run your 
programs on any card? The DirectFB MPEG2 videoprovider can even do 
software MPEG decoding when necessairy. And there is a DirectFB port for 
the dbox2 too, so you can use a silent 'real' STB in your living room 
and let the Harddisks mounted via network somewhere where the noise does 
not matters.

We won't do this too soon, but the current AV7110 based PCI cards might 
stay the only cards ever which implemented this OSD API.
