When I worked a service desk, I was always being asked by patrons if we
had something like Quicken loaded and available for the public. While
I think that those patrons were misunderstanding the complexity of
financial software and the efficacy of sharing it in a public place, I
think there is a niche out there for people who want online financial
management help.
Mint is a site that offers this sort of
feature. It is free, online and offers ways to chart what you are
spending your money on, interest rate recommendations, bill alerts,
watching for unusual spending, and much more. Definitely a place to
send those Quicken nomads to.
