From arhag:

Also, @svk31 it would be really cool if you can get the script toast used and build it into bitsharesblocks.com. It doesn't have to update continuously if it's a resource problem. Even once a day > would be very useful. And it would be nice to keep the daily history of the distribution.

Amount of BTS stake in genesis that has not been claimed (I believe this is the 579 million BTS figure > from bitsharesblocks.com, correct?)
Amount of BTS stake in sharedrop that has not been claimed because it has not yet vested
Amount of BTS stake in sharedrop that has vested but has nevertheless not yet been claimed
Amount of BTS stake tied in collateral (bitsharesblocks.com already has this, it is currently 202 million > BTS)
Amount of BTS stake tied up in market orders
Amount of BTS stake that is not one of the above but still is voting for the null slate.
