[Ietf-caldav] Recent Mozilla or other CalDAV client development builds?

[Kervin L. Pierre]

Hello,

I am looking for a CalDAV client for
tracing network activity so to make
sure that mine is doing the right
thing.

Heard Mozilla has an advanced client,
but does anyone have recent binaries
of their that client ( is it Sunbird
or Lightning ) with CalDAV support.

If not, are there any other CalDAV
implementations that I can download
and use?  It could be binary since I
just need the network traffic.

Thanks,
Kervin
