It shouldn't be a problem to connect from 8i to 10g as long as you don't try to 
use any 10g SQL*Plus features (e.g. purge recyclebin).  Shouldn't be a problem 
to install multiple clients on the same Windows machine either - just be aware 
of which one you're running your executables from  to make sure you're 
accessing the correct tns config files, or set your TNS_ADMIN variable to 
override the defaults and point to a centralized location.  If you have 
trouble, just search metalink for  "oracle.key" and/or "tns_admin windows" and 
you should find some notes to get you on the right track.  This probably goes 
without saying, but just in case you're not aware, you'll want to make sure you 
install the new client in separate directory from the existing client.  Also, 
why install the 9i client instead of the 10g client?
