File-backed file system manipulation question

Hi All,

I have seen questions regarding mounting and dealing with root owned data, but 
nothing that appears to solve my particular issue.

I am creating an application that needs to mount VM images and do some 
manipulation (swap kernel, change fstab, etc). Most of the files and directories 
in the mounted image are owned by root, but of course I don't want to run the 
application as sudo. Is there anyway to get around using root at all (I can give 
any user access to a specified mnt point in fstab)? This is probably more of a 
Unix, systems question, but I'm interested to know if others have dealt with 
this in the Python domain.
