Does anyone have a particular recommendation for a module? Writing the XML isn't the issue for me - it's more the parsing iCalendar files. Suggestions?

I second Data::ICal - it's dead easy and it can read and generate. It 
uses Text::vFile underneath for parsing.

Data::ICal::DateTime basically just adds DateTime support in and, you're 
right, it's dog slow (fcvo 'dog'). It's mostly my programming rather 
than yours I suspect although also partly DateTime (correctness comes at 
a price) and also the overhead of working out recurring events and 
whatnot.
