"Apt-Cacher-NG does not require neither an interpreter, nor a web server and not even a huge runtime library. It does never fork after server startup, it does not create flag files, flock() files or similar fun. Instead, it uses native system functions (mmap, sendfile) to operate with few overhead.
"Apt-cacher-ng caches the repo’s from the different versions of ubuntu quite nicely. It even nicely supports the different installs of intrepid in my home with different personal package archives (PPA, you know as in ppa.launchpad.net/*)."
