Simple Solid Fog Question -- What does 5' mean?

[two]

Solid Fog reads, in part:

___________________________________________
Solid Fog
[...]
This spell functions like fog cloud, but in addition to obscuring sight, the
solid fog is so thick that any creature attempting to
move through it progresses at a speed of 5 feet, regardless of its normal
speed, and it takes a -2 penalty on all melee attack
and melee damage rolls. The vapors prevent effective ranged weapon attacks
(except for magic rays and the like). A creature
or object that falls into solid fog is slowed, so that each 10 feet of vapor
that it passes through reduces falling damage by 1d6.
A creature can't take a 5-foot step while in solid fog.
___________________________________________

What does "progresses at a speed of 5 feet, regardless of its normal speed" mean?

Does it mean if your move is normally 30'/round, it's now 5'/round?

Can you run at a rate of 5' X 4 = 20' in a Solid Fog?

Can you move 5', and do a MEA?

Can you move 5' and attack?

Can you double-move -- going 10' in the Solid Fog?

Is moving 5' in the Solid Fog a full-round action or something, or just a normal move? And if it's a normal move, how come you can't move 5' twice? Or can you?

*confused, as normal*

Yes

Can you run at a rate of 5' X 4 = 20' in a Solid Fog?

Since you can't run when restricted to half-speed, and generally moving at 5' is worse than that, I think running is not possible (nor is possible to charge).

Can you move 5', and do a MEA?

Yes

Can you move 5' and attack?

Yes

Can you double-move -- going 10' in the Solid Fog?

Yes

Normal move, basically this spell changes your speed to 5'. At least that is the way I read it.

Hmmm... good eye on this.

I'm gonna throw my vote in with two, there.
