The below example shows how to drag a spot anywhere inside a window and make the whole window follow the mouse. Although it uses a GUI window, it could be adapted to work on any particular window, or even on all windows.
Code:
gui, -caption +0x40000  ; 0x40000 is WS_THICKFRAME (needed for AlwaysOnTop).
gui, add, text,, Text to display
gui, show
WinGet, GuiID, ID, A
WinSet, AlwaysOnTop, On, A
return

~LButton::
CoordMode, Mouse
MouseGetPos, MouseStartX, MouseStartY, MouseWin
if MouseWin <> %GuiID%
   return
; Otherwise, track the mouse as the user drags it:
SetTimer, WatchMouse, 10
return

WatchMouse:
GetKeyState, LButtonState, LButton, P
if LButtonState = U  ; Button has been released, so drag is complete.
{
   SetTimer, WatchMouse, off
   return
}
; Otherwise, reposition the window to match the change in mouse coordinates
; caused by the user having dragged the mouse:
CoordMode, Mouse
MouseGetPos, MouseX, MouseY
DeltaX = %MouseX%
DeltaX -= %MouseStartX%
DeltaY = %MouseY%
DeltaY -= %MouseStartY%
MouseStartX = %MouseX%  ; Update for the next timer call to this subroutine.
MouseStartY = %MouseY%
WinGetPos, GuiX, GuiY,,, ahk_id %GuiID%
GuiX += %DeltaX%
GuiY += %DeltaY%
SetWinDelay, -1   ; Makes the below move faster/smoother.
WinMove, ahk_id %GuiID%,, %GuiX%, %GuiY%
return

Available in the scripts showcase section ? Yes, or ?
Yes, yes, yes (the "bit" would answer @ Tron)

It seems a little too obscure for that. But it's here in case anyone ever searches for such a thing.

I'm not a very expereienced AHK user, so my understanding of this script is superficial to say the least. I get the jist of it, though. Would it be possible to apply the concept to all windows, with a hotkey like ALT+Lbutton, instead of just the gui AHK creates? (Linux style)

Here is a revised version that works on any window. Since there is more interest than I expected, I've put it here: http://www.autohotkey.com/docs/scripts/EasyWindowDrag.htm

Chris, did I ever tell you you're my hero? It took all of 30 seconds to get one of my fave *nix features ported. Shocked
