I was talking about the server deva approach.

It makes no difference how deva is implemented, it should be the only
part which is os dependent. If deva is a server the virtual drivers
have to be written separately. If deva is a library they have to be
written inside deva. In the end it doesn't make any difference you
have to write them.

The ddf has to be self containing. But as the drivers don't need all
fancy c library functionanlity the libraries can be very slim.
