I see, didnt noticed that eariler.

Installers could detect if any JRE is available, then download/install them if 
needed. (commerial installers like http://www.advancedinstaller.com/ or 
http://www.denova.com/  does that), if not make a notice to download it from 
sun's page.

As for whether installer can uninstall other applications, its yes (esp if you 
have admin privillages in windows). An example is Google pack - 
http://pack.google.com

A batch file can be very written quickly eg..
:: LilypondPackageInstaller.bat
start /wait "ftp://blabla.org/java5.exe";
start /wait "http://blabla.org/lilypond.exe";
start /wait "http://blabla.org/jedit.exe";
start /wait "http://blabla.org/lilytool.exe";

But can the user might be confused after installers after another installer 
popups is a question. Maybe setting up a webpage like "Ultimate guide to 
lilypond on windows" with links to all the installers can be as easy but I 
thought the flash tutorials http://web.interware.hu/fodber/lilytut/ was quite 
good already.
