Okay, I started to look into this, about time huh? :)  I did notice a bug in the
horde/lib/Data.php version I'm using.  Not sure if you say this:

Around line 255 in the _build method:
                if ($data[$i]['name'] == 'BEGIN') {
                    $object['objects'][] = $this->build($data, $i);
                } else {
                    $object['params'][] = $data[$i];
                }

that first match needs to call "_build" not "build" (note the underscore).  I'm
assuming this is a recursively called routine.  When I try this out, it all
works quite well, except there is not data.

Question 1: Does PHP have a similar module to the Perl Data::Dumper routines?  I
want to dump what I get back from the Data_rfc2425::import method, cause it
seems to be an empty set to me?  Not sure if you've tested all this, but I just
can't seem to get any iCalendar objects to import properly, it flips through the
recurive calls, but it seems to lose the data.

I compared my example vCard to an iCalendar

Note that the iCalendar object has a recursive BEGIN block.  I can't seem to
figure out enough about PHP (yet!) to find where the data is going, but it sure
seems to go bye bye!  Any thoughts?  Have you successfully seen an iCalendar
object get imported?

Thanks in advance, at the very least I'm learning! :)
