instead of storing files on dropbox, you might consider running a small
CalDAV server. CalDAV clients connect to the caldav server to
synchronize, but typically cache all content.

IOS devices have CalDAV syncing built in. Android devices can add caldav
syncing with either a free connector or a $2.99 connector (both from the
google play store). OS X i believe also has CalDAV syncing built in. The
sunbird client (and thunderbird integration) from mozilla works great
for windows and linux machines. AgenDAV works as a fairly solid web client.

sabre/dav is a solid and easy to set up server (http://sabre.io/). the
stock installation would require a web server, php, and mysql. i've
written an alternate sabre/dav implementation that replaces mysql with
filesystem storage - you are welcome to it if you don't like running
databases (though it would require a bit of extra code to do handle the
type of authentication system you'd choose to use).

you could also just use google, as they provide caldav access to the
data (to which all the normal bits of caldav clients would apply -
they'd cache all the content and sync changes from google).

most caldav clients would save your password, so you wouldn't be
prompted for your password each time you started them up.
