I am sorry, but I may have created more confusion here. Everything
that's written above is correct, but it's even simpler than that.

You can *always do partner_id.the_field_i_need* and it works; no matter
if it's a company, a person, a representative of a company... The v7
model ensure that every record holds the right data. (e.g. "John Doe,
Acme" has the pricelist of Acme).

So, in your own module, you don't need to worry at all about
commercial_id. That's why community module should work nearly as it.
