Interesting concept, so I though I would try it out.  Here's what I did:

1.  Tool-chains and host support packages already installed.
2.  Built and installed fakeroot-ng, http://sourceforge.net/projects/fakerootng/
3.  commented out my /etc/sudoers entry that ltib requires.
4.  Modified ltib to use fakeroot-ng: replaced  sudo  => "sudo" with
sudo => "fakeroot-ng"
5.  If run already once as root the rpm database is owned by root,
chown as required.
6.  Ran ltib for one of my platform configs with --no-sudo to skip check.

Building now without seeing any issues.   Not done yet as it this
platform takes about an hour to complete, but I have some new rpms and
a rootfs under my id.  Nice.

So, I decided to go re-visit #1 to see if I can install the ltib host
rpm's and tools as a user.   Cleaned all traces of ltib from system.
chown'd /opt as myself.  Get through rpm-fs, fake-provides, but fails
on mkspooflinks:

Build time for mkspooflinks: 3 seconds

mkspooflinks                error: unpacking of archive failed on file

Not sure of the error, but would be interesting to get full ltib under
user id's since this may help in the long-run.
