How work's Drupal developments using SQLSrv driver?

I have some questions about this scenario:

1 - If I distribute a development in drupal using MSSQL as Database Server (http://drupal.org/projects/sqlsrv) that is not under GPL licence, the functions and/or procedures stored in that database can be encrypted? Notice that in this case I didn't encrypt the drupal code.
2 - If I use Drupal to interact with data generated and managed from a propietary software (which can't be redistributed), can I via contract or other negate the possibility of a redistribution.

The object of this is to protect the internal behavior of the propietary software so any comment of what can i do in these scenario will be appreciated.

Thanks

PD: Sorry about my english.
