It is one of many Con-Lang (Constructed Language) projects in existence. As far as well developed conlangs, it's quite wel established. (Esperanto, Slav, Tengwar, and Klingon have far more established followings)
ConLang is to linguistics as geofiction and worldbuilding are to the environmental sciences: taking the well known principles and applying them in new ways.
Me, I get kind of lost in the details of Bilandin. However, I try to follow along out of linguistic interest. I've studied several languges: English (native), Spanish, Russian, Latin, Japanese, Klingon, Heraldry, and Arabic, plus several programming languages: BASIC, C/C++, Python, and NewtonScript; I've only developed useful vocabulary in English, Spanish and Russian, and BASIC and C++. (Yes, heraldry has its own language, a bizarre hybrid of french, latin and english vocabulary and its own syntax.)
From the standpoint of being a real language: yes, it is sufficiently developed to be spoken conversationally. No, it's not a common one.
