I'm close to finish a lilypond webservice that could be used on the internet or
in the local network. I think that would be ideal for that as can be used from
any browser.

I'm working on this idea for the upcoming iPad. I would love to be
able to sit with my instrument and notate with the iPad on a stand or
table. The first approach I'm going to try is with a RESTful web
service backend app running on my desk computer. If I don't get the
performance I want with that, I'll create a Cocoa server app with
direct sockets.
This seems like a very doable project and I'm looking forward to
giving it a try. Waiting for my iPad!
