[otrs] Support for customer/company/employee/contact persons

Hi OTRS, as far as I saw and understand OTRS (1.0, 1.1.1), there is currently only the single caller/mail writer as customer model implemented. I am looking for support for a customer (which means a company with possibly several employees/ contact persons) model, which would make it possible to use OTRS in much more companies as with the simple structureless idea of the "patient". If there are such intentions and manpower is the missing thing, I'm willing to invest into such an implemention with a little team of software developers. So pls let me know, if I have overseen existing things, or if anybody else in interested in such a beast. Greetings Paul (aka Gerold Gruber)
