1) and 2) is agreed but can live with it, 3) could you explain it? I mean
using simple HTTP upload requires nothing more than a standard web form with
<input type='file'>
Of course more flexibility can be provided within a java applet. (Selecting
more than one files, upload monitor etc.)

that lets say you are on windows, you only need a LilyTool for jEdit, (with
has all the wizards and synatax colouring), it will be simple for you to use
Lilypond. Lets say on a Linux machine which have problems installing
Lilypond, perphaps a small python client script could be ran like "python
LilyPondClient.py foo.ly".

change like LilyTool to implement the HTTP upload method. But I wonder how
you will implement the php? Will you call the Lilypond process stright from
php [proc_open()]? or would you open a socket to connect to a Lilypond
Server [fopen() or socket_create()]
~~~
My idea was to have a single machine which has web server (with PHP) *and*
lilypond installed on it. I can use eg. [system("/path_to_lily/lilypond
just_uploaded_lilyfile.ly")]. Then I let PHP to read the output files, and
create a html report with links to them.
With your ASCII keys:
L <--P <--W
This could even be a first step to either Scenario #1 or #2.
[I have to admit that I haven't ever used socket connections, so this may be
the reason I leave it out of my thinking, but I understand how much more
advanced systems can be built over them.]

64Mb, but its harddisk is not working and cd-rom does not boot up. I might
try to fixing it and setting it up as a POC, and also if my upload speed of
10KBytes/s at home wont be too much of a disappointment.

I need an online computer with Apache-Php-Lilypond installed on it. I could
turn my own machine to it (actually I did it), only problem that I have a
slow modem connection, which could do it for the first public tests, but I
cannot afford to keep online all the time (money:-().

used just to bridge from the coLinux guest to host machine, but it would be
a trouble on the public access server.

ROOT? Never! Are there any good reason to run it as root?
