That's OK, as I can just memcpy from my mapped buffer. There are cases
where I would like to just write to disk directly from the buffer, but
precious few.

If someone wants to operate, say a PS3000 remotely, the net module
can use sockets to move buffers. I'm happy with that.

So all I'm looking for at the moment is some sort of means to negotiate
frame formats.
