If EDC-ECC are consistent with user data there's no point in writing RAW
sectors. It's possible to write inconsistent EDC-ECC blocks using a
generic mmc raw capable burner and right software. Under Linux only cdrdao
can do this at the time of writing.

It's far from being similar. After setting up the writer for raw session
writing it's necessary to perform SEND CUE SHEET commad which describes in
depth the TOC of the disc. Here you must specify data form of main data,
and this will show up in the TOC. Of course you can write your data track
as audio but this won't be useful, I bet :-)

Not as you are intending.
