Ok Ok, im really going nuts here. I have absolutely no experience with animation, riggin etc.
So i read and read but it seems i can't find the proper info i need to make this rigg that i want.

Ok ok, here is a pic of the object that i need to rig.
This is some monster that i made, the client insist that i should do the animation and rigging, because he is a cheap motherfoker ... But never mind this, i gotta make it...

So, i try the simple solutions that come with XSi - Create spine, create Tail etc... but they dont work as i need them.
I managed to rig it with Tail, but this thing is kinda simulated ? And i just can't figure out how to put some control point's where i need them to animate this rig.
The spine just dont behave like i want it to. It has 2 control points and its a pain in the ass/ impossible for me to create this snake-ish motion.

So what i need is something like this on the picture - a couple of bones and controllers (in the red). So when i move the controlers i get this smooth chain movement, like for example in the Spine rig that comes with XSI.

I feel like its a simple rig ??? Am i right ? Please someone, give some info/tutorials/ or just explain how to do this.

I'm not an expert on what you're trying to do but you could give MT_spring a try.

If you draw a curve with 4 or 5 points along the length of the limb you want to move, you can use a couple of options under the animate/create/skeleton menu

First create chain from curve - small number of bones (to match number of points in curve). Don't constrain to curve.
Second create control spline - high number of divisions.

The parent the light green diamonds to the nearest bones, and animate the bones in FK, you will get a spread along the length of the curve. If you want to get more detailed you can animate the position of the green diamonds on top of the bones.

Well, i found this scrip over at some closed long time ago thread in Cgtalk.
It works really well for me... i managed to do the animation at a satisfaction level :)

Thanks guys, for the replys and help!
Code:
set oSelList = GetValue("SelectionList")
set oItem = oSelList(0)
strStringedSel = oItem
set oGeometry = oItem.obj
oNumberOf0DGeometries = oGeometry.Nb0D

SetUserPref "SI3D_CONSTRAINT_COMPENSATION_MODE", 1

for i=0 to (oNumberOf0DGeometries -1)
set PrevNull = GetValue("SelectionList")
CreateClusterCenterWithNull strStringedSel & ".pnt" & "[" & i & "]"

if i>0 then
set CurNull = GetValue("SelectionList")
ApplyCns "Distance",CurNull ,PrevNull , true
end if

next

SetUserPref "SI3D_CONSTRAINT_COMPENSATION_MODE", 0


'_________________________________________________'
''''Change the variable below to change the number of bones'''''
'--------------------------------------------------------------'

NumberOfbones = 5
CreateChainfromCurve oItem, NumberOfBones , True

wmendez also mentions in that thread using Isner Spine as alternative.
