Alright. The only thing I'd say about this is what most people have said already. Maintaining multiple ports bears real, non-trivial cost, varied by the libraries used, and it'll be a long time before the Linux marketshare is large enough justify the investment to most dev teams (in spite of being disproportionately vocal). Imperfect as they are, P&W are needed to bump those numbers.
It seems like asking for Linux ports is kinda your thing, so I'll leave you to it.
