I've been using a new service from Google for the last two weeks and love it (so far).
It's a realtime on-line spreadsheet.
Great for schedules
Script breakdowns
Budgets
Equipment lists
Crew calls
Anything where you want a bunch of people to be totally up to date on listed or mathematical data.
To try it out - it's Free, BTW - Google "Google Spreadsheets" and sign up. Once you create a spreadsheet you can allow any number of guests into it with either read only or read/write privileges.
And it's real-time.
And it's stored on-line so it's accessible from anywhere.
Check it out.
