a) Source code added to github. This should have been made instantly after announce but amount of other needed actions and involvement was a surprise to us.
https://github.com/jdgdredd/FairQuarkb) There is also new giveaway coming up soon on Poloniex for anybody to grab some FRQs free.
c) OSX wallet under work and coming soon.
d) ABE fork coming soon too as requested (keep an eye on same github account)
Great.
Another simple utility would be a paper wallet, just fork & adapt one of the
existing ones.
Less simple but required in the long run would be a smartphone wallet, and much advertising/marketing.
