Future Tech Mod?

[Ravenloff]

I would be really interested in working with a team that wants to extend the game into a couple of extra eras. What I'd really like to see are SMAC-type things like

1) Cities on the ocean
2) Underwater highways or vac-trains (a la CtP)
3) Future combat units
4) Terraforming abilities
5) Future promotion types
6) Somehow, I don't know how, an orbital layer with cities in space
7) Great generals. (does Civ IV have these already?)

This is one of the future parts of my mod, really. Ideas I had:
SMAC-style Satellites, perhaps a precentage bonus instead of a flat bonus.
Laser troops. I mean, c'mon, lasers!
Fusion Power Plants
Other stuff.
