Some questions about ruleset design

Hi

I am building a large data set for rndCiv
  http://banjo.actrix.com/code/rndCiv
and i have a few questions about the how the
rulesets work..

1) can i create a small wonder? a building that
   only one nation can build, by setting
     name        = $name
     equiv_range = world
     equiv_dupl  = $name

2) is the 50 building limit going to be changed?

3) what happens if more than one tech has the same flag?
   especially these flags Boat_Fast, Bridge, Railroad, Farmland,
   Fortress, Watchtower, Airbase, Reduce_Trireme_Loss1,
   Reduce_Trireme_Loss2

4) Do units with the "AddToCity" flag cost 1 population
   when they are built?

5) would it work to create an Arcology building with the
   Size_Unlimit flag set at 24?

and can i make a request for a new unit flag "HiddenNationality"
which hides the nationality of a unit, setting it to Barbarian?
This would be useful for Privateers and other criminal units.

cheers
