Thanks for the patch! Looks good and I'm planning on submitting
something similar in Horde cvs. My current version is here:

http://hg.pardus.de/cgi-bin/hg.cgi/horde/HORDE_CVS/file/631b399d48f1/framework/HK-GW-FreeBusy_trigger.patch

I did hit some other issues here which I need to fix first in order to
check the whole thing and finally submit it to Horde.

Cheers,

Gunnar
