Where is the problem ?? I think Apollo did it by hacking the library function
open. First do a lstat , if it's a symlink get it , replace all the env
variables endif , than open the file.
Every Systemcall that uses filenames must be fixed too.
And you have to relink all applications against the new library.

P.S.
I would prefer a generalized version of the universe concept.
