Oh well, I have changed login name since I made it originally: Here is a revised version of Pike from post #5
This script relies on auto-swooshing of windows by Spaces/Expose; that is, when you select a window in another space, that space is activated/you are taken to that space (pick your view).
You activate auot-swooshing by entering this from the command line:
-- Pike http://macscripter.net/viewtopic.php?pid=154619#p154619
-- © McUsr and put into public domain you may not post this anywhere else, what so ever!
-- Added a try block, since some applications doesn't allow you to set the visible property
-- of a window.
-- 2013/07/08
-- When saved as an app, and the LSUIElement is not set (Application is an Agent): then
-- The script will err, since there is no frontmost proces. I have "fixed this" by setting "me"
-- as the frontmost process in those cases.
-- Some windows of some apps doesn't even have a visible property.
-- I have also forked out a script object for practical purposes, in the post above.
-- I have removed one more bug, the issue was when there were just one window in this
-- space, and windows in other spaces, and I tried to hide the window, and make it visible again,
-- then I would remain in the other space.
-- Ok, so I removed the choose dialog for the case where the app has just one window totally in every space.
-- There are probably still some glitches here, when an app isn't scriptable and so on, but this is as good as
-- it gets from my side, to pick a window among those you have in the current space, or select from all spaces
-- if you have no more than one window. If you have none, then you command - tab to the app. The script is in
-- post #7 together with a skeleton for an app, so you can use it from various places.
-- Invisible windows, that should have stayed invisible started to turn up as a result of former fixes. It is updated in post #7.
-- Now it moves you into the space where a window resides, if the window you chose didn't reside in the current space,
-- (if you had just one window in this space, you'll get the opportunity to select windows from other spaces, if the app has any).
-- It is all in post #7.
-- Factored out a subroutine, and tested it thoroughly, with document based and non documentbased apps. It should work as intended
-- for applications that are scriptable.
-- One last bug is fixed. The problem was not getting the window to front, when the window is residing in another space.
-- I had to differentiate between cases where there were just one window in another space, and more than one.
-- Perfect, as far as it goes.
-- Apart from when there were multiple windows in the current space. That is fixed now.
# Totally fixed, the right version too..
# fixed bug, when an app that we want to display windows for are somehow busy.
# implemented a workaround for Smile. Thanks to kel!

Then you just activate spotlight, type pike, and off you go. (You should set LSUIElement to true.)
But before you do that, be sure to comment out the quit, and drag it into the Dock while it is running. Then you’ll kill it from activity monitor, and then you set LSUIElement to true with Xcode or Property list editor. 
That is fixed now.
