[otrs] OTRS as an internal help desk system

Hi, Anybody tried to use OTRS as an internal helpdesk system for a whole company? I mean for example if someone from accounting dep. has a request from IT dep. he send his request throug the web interface of OTRS, if someone from human resources dep. requests something from another department he sends a request from OTRS etc. Even if nobody uses OTRS for this aim, is it logical to use OTRS this kind? Thanks
