Desktop space reservation

This might be a bit of a stretch, but is there some software or method available to reserve desktop space, but allow certain programs to use it? Sort of like dividing the desktop so that maximizing a program only takes up a certain amount of the screen?

EDIT: if at all possible I'd like to be able to maximize another window inside the reserved space.

Solution 1:

I'm not sure I understand. Are you lookign for something like this: MaxTo

There is a few more of them here: Windows Split Desktop Utility

Solution 2:

this CAN be done with JetToolBar, which is a freeware. This will install a sort of toolbar / launcher, which is what it is. What you need to do next is run this toolbar as NOT always-on-top (just see the program options), and use another program to run the program that you want to run (that I don't know of but any will do) as 'Always on top'. (See download.com, many program can make another one run on top of others).
