Hey Dirk, how far have you gone into the iCal integration? I am starting to write some code to try to "export" to iCal using as a base the outlook procs ... doing this in my spare time so going quite slowly (haven't done any OpenACS work in quite a while) but getting there ;)
My idea is to have a library to export (just formatting one calendar into iCal RFC's 2445) and then be able to upload from iCal (apple's Calendar tool) using webdav to OpenACS's calendar....
Cheers
/B
