Being the Desi Lingua franca, Hamari Boli (natural Hindi-Urdu in Roman) is the only option to reach all Desis equally. However, the crippling Devanagari-Nastaliq Digraphia renders any kind of Opensource collaboration IMPOSSIBLE among Devanagari/Nastaliq/Roman writers unless each collaborator knows all three scripts. Hamari Boli resolves the dilemma by using neutral Roman script to create equally accessible opensource content and thus, for the first time, enables 'Open Collaboration' among the whole spectrum of Devanagari-Nastaliq-Roman readers & writers.
