VCS download from link for PDA, Smartphone etc.

Do you have a question? Post it now! No Registration Necessary.  Now with pictures!

I would like to put up a calendar on our site where people can download
birthdays, reminders, to-dos etc. in VCS format.
Does anyone know of any software that I can use that will allow me to
make a calendar and then the entries I put in be converted to VCS links
so once clicked on (or R-click, Save As...) that they can be then
dragged to the smartphone, pda etc.
