Well, I don't know how to name it and how it will looks, but I will try to explain the principle of how it works.
This grenade works in standard time as usual grenade. After activation it creating round field which have size as round of Shield grenade and behaves as usual water. It means that any players or objects which have got in this field will float, as in the water. As for water, it's possible to give damage parameter for this fields. Fields have more transparent color of current water/acid color and at interaction let out sparks instead of water splashes. If two fields are crossed, then they will work as one. As well as 2 water regions.
- Hmm... If you mean the players would be able to float on water then this seems impractical - the players will be unable to move since they're in a bubble. I think a boat would be better
- If you mean the players would be able to move within the shield as if they were in water then I think this would be a fair replacement for slow motion in PB2 multiplayer
- Poison.
- EMP. Shut off vehicles for a while.
- Healing.
- Pushing. Push all objects out of field. Small work time.
- Black hole. Attracts all objects in the centre of effect area and causes damage. Work only 5 seconds.
- Mines. Can be same types as grenades.
- Flashbang, Smoke, Napalm. You know, some topics about that.
Mines - should be invisible and shouldn't be fatal
Flashbang - I don't think this would work since they would be shielded by their visors (but that doesn't matter). Instead how about some sort of jammer like CPT said but it incapacitates the player (audio and visual effects of static on screen) by overloading the on board computer with data (so this applies for robots also). After 5 seconds or so the visual and audio effects would cease but the player would be unable to tell the difference between allies and enemies.
I think the rest of 'em are good ideas
Cpt Epsilon Tex"]Hmm EMP. Only for vehicles? What if EMP grenade disabled nearby enemies' HUD for 7 seconds. I mean health, and things like that, and wouldn't show names so they cant tell if you are an enemy or not. Maybe a bit bad vision for 3 seconds. I mean like ants would walk over the screen. You know what I mean
Flash: What if flash would make enemies blind? And would not hear shots. For 2 seconds.
Good ideas eh?
EMPs should immobilize both vehicles, robots and armoured suits unless these suits are mechanically powered.
I don't think disabling the HUD would really add anything other than being a nice effect, though with friendly fire in PB2.5 it would be interesting if you don't know who your enemies are.

Personally I'd like frag grenades to be implemented
It creates a smaller explosion than the Grenade C-00n but shoots shrapnel at all directions at fairly high velocities(same as the broken glass in PBFTP)
