Apart from the sharedrop, I see the good news in this: every piece of ecosystem infrastructure (e.g. mobile wallet) written for BTS can be easily forked to work with IDentabit.
So IDentabit can act as a legal safety net for money invested in building BitShares ecosystem.
I can go to my investor and say this: "Invest in my BitShares-based company now and if things get unsafe in legal terms we have a solid Plan B: we can always switch to IDentabit".
Sounds like a good argument to me.
