I'm looking for something that by all accounts shouldn't be too hard to find. I've failed to find it, though, which leads me to believe that it might not exist. Therefore, I turn to the good people of the web for help.

I'm looking for a plugin or macro for Outlook that can invisibly (without prompts or notices) create an iCal (.ics?) file that is then sent via FTP to a remote server. The idea is to be able to subscribe to this with a Mac (or phpiCalender etc) elsewhere. I would like the plugin to update the file whenever the local calendar is updated. And to keep track of categories. I'd also like it to support both appointments and to-do lists, if possible.

Does anyone have a bit of spare time to put something like this together? From what I've seen so far trying to find something like this, it would be very very popular indeed.

Maybe this is one for the LazyWeb ...
