OMET: Online Music Editing Tools feedback?

[Mike Blackstock]

If somebody could have a quick look at http://www.vex.net/~mikeb/omet
and tell me what they think I'd appreciate it.

Keys and stuff are missing but all that code is ready to upload, as is
code for producing midi 'on-the-fly' and generating lllypond source.
Also I can demo real-time collaborating shortly - user A enters a note
and it also appears on user B's screen, and real-time lilypond
compilation is straighforward, down the road. A secure 'lilypond
rendering farm' is what I have in mind - the webserver communicates
with the lilypond servers etc etc.

What I'd like to know specifically is whether the approach is sound -
being able to treat the screen as if it were a blank sheet of paper
where you can enter notes anywhere and in any order? Before I start
uploading other stuff, is there something I'm overlooking in the basic
interface?

Thanks a lot. I think it works across all browsers, though someone
reported problems with FF 3.6.3 on some version of Vista, and IE 6 has
the png bug that I gave up on. Also Google Chrome doesn't properly
handle the turning off of the cursor it seems, at least on my system.
