Why there is any distinction between, say, gcc and X?
KDE and Midnight Commander? etc... Why some of them go
to /opt while others are spread across dozen of dirs?
This seems to be inconsistent to me.

I won't push my solution to anyone, just going to show you
how does it look:

# ls /usr/app -1
Linux-PAM-0.75
MPlayer-0.90rc4
SDL-1.2.6
acrobat-5.06
acroread-5.0.8
alsa-lib-0.9.0beta12
alsa-lib-0.9.7
alsa-utils-0.9.0beta12
alsa-utils-0.9.7
apache-1.3.24
atk-1.2.4
audiofile-0.2.3
audiogalaxy-0520
autofs-4.1.3
bash-2.05b
bglibs-1.005
binutils-2.15.91.0.1
bridge-utils-0.9.6
bsdftpd-6.0-ssl-0.5.2
busybox-1.00-pre6
...

Typical package under /usr/app:

# ls -l /usr/app/gcc-3.4.1
total 12
-r-xr-xr-x    1 root     root         1429 Oct 25 13:39 !vda_install
-r-xr-xr-x    1 root     root          874 Sep 15  2003 !vda_install_root
-r-xr-xr-x    1 root     root          157 Aug 17  2003 !vda_ver
drwxr-xr-x    2 root     root          360 Oct 25 13:39 bin
drwxr-xr-x    3 root     root           72 Jul 15 16:54 include
drwxr-xr-x    2 root     root          224 Jul 15 16:54 info
drwxr-xr-x    3 root     root          336 Jul 15 16:54 lib
drwxr-xr-x    3 root     root           72 Jul 15 16:54 libexec
drwxr-xr-x    4 root     root           96 Jul 15 16:54 man

This is how it is made visible to the rest of system:

It's pretty modular: I can remove and install packages
as needed, I can go back to older versions to check
regressions etc...

BTW today I just added uclibc and some uc-compiled apps to the mix.
They coexist nicely with the rest of the system 
(I needed only some almost trivial tricks)

uc-Midnight Commander is 3 times smaller than glibc one :)
