Nonono: I meant exactly to do an open card with an open dsp software. Next time hardware producers will think twice before refraining from disclosing card details...
After all, most producers didn't ever need to disclose their firmware as long as it is a binary file to be uploaded to the card. But still it took a lot of time to have a working ADSL driver under Linux, just because producers didn't want to disclose port assignments and the like. I.e.: they preferred not to disclose anything instead that just refraining to disclose the firmware, which would had to be enough for their purposes.
This is a behaviour that the linux community shall discourage. Designing an open hardware and software solution for ADSL connection would be a great way to avoid something like this in the future... You don't disclose? I offer an alternative which bypasses you.
The matter is not so easy, however: the ADSL standard is complex and dsp software has to take into account a lot of ADSL "flavors" (DSLAM producers often offer enhancements to the standard way), but it shouldn't be too difficult to the linux community to put together the needed gray matter...
Anyway, all these speculations are definitely OT. Sorry about that.
Cheers,
giampaolo
