in software sources i see a lot of links that don't link to lanchpad.net 

```
http://deb.playonlinux.com/ oreiric main
http://dl.google.com/linuxearth/deb/ stable main
http://linux.dropbox.com/ubuntu precise main

```

i was wondering: can i add a regular download link in my sources.list.  

here is what i mean to do.  

this is the download link for [notepad++](http://notepad-plus-plus.org/)(an example)

```
http://download.tuxfamily.org/notepadplus/6.1.3/npp.6.1.3.Installer.exe

```

i wonder can i add this(or an other) link to download the latest version of notepad++(or any software for that matter) and every time  

there is a new version of notepad++ i can install the latest via update-manager.   

this is exactly when adding vlc(A example) in the sources.list. And when the software.  

has been downloaded to run a command like `wine npp.6.1.3.Installer.exe /S /Silent`  

for silent installation.
