Hi,

You could always rename Mathematica.app file for version 7 and 8 
respectively,

Suggestions,

Version 7.0
Mathematica.app -> Mathematica7.app

Version 8.0
Mathematica.app -> Mathematica8.app

You can put both the installations in Applications or create a sub 
directory "Applications/Mathematica/" and put everything in one place. I 
have all the Mathematica installs starting from version 5 in one 
directory.


Another useful trick I use is to use version specific FE preferences. 
This way I can maintain multiple init.m files. Just incase of some weird 
version specific FE corruption of init.m file my other Mathematica 
installs are not affected and  specifically on Mac this was the only way 
I found I could run Mathematica version 5.

In Version 8.0 you could goto,

Mathematica >> Preferences >> System >> (Check the box under "System 
Settings"-> Create and maintain version specific front end preferences.)

Hope this helps,

Vivek J. Joshi
