There's the small problem of what to do with all the info in the m files that players aren't supposed to know, like CA-learnt hab values and such.
But that could be solved by inserting a "filter" tool between what Stars! gens and what SAH lets players download.

• While in M files generated by Stars! 2.6J RC3 and 2.7J RC3 that data is present, and can be pretty easily extracted if you know decryption and the blocks structure.
  
• But Stars! 2.6J RC4, which is used by SAH, does not have this problem at all! In case of M file generated by 2.6J RC4 that block is still present in CA m file, but all of the data except hub values are zeroed.
