We use something like this at PARC.  It's incredibly useful, since
it allows you to have multiple versions of software around and turn
them on or off individually without having to rename executables, but
I'm always running into hard-coded limits.  My $PATH is nearly 1k bytes
long, and if it gets any longer random programs start misbehaving in
various strange ways.  Same with $MANPATH.
