So by use you mean "disk space filled with different distros," right?

Yes.  You probably only need around 5GB for each install.  But you can 
check when you do the install.

If it were me I'd make the whole disk an LVM partition and use that for 
each install.  You don't need more than one volume group but that trades 
flexibility for separation.  There's an extra layer of abstraction to 
keep track of but I think it's worth it.

If you want to see what that looks like you can come to installfest 
tomorrow and we'll show you.
