Another CalDAV Server

I see that Jari Urpalainen has written an CalDAV Apache module to support some basic CalDAV functionality.

Excellent.

Meanwhile my own CalDAV server is going through a period of stabilisation before I start in on some of the handling of "Principals", probably next month.

And CalDAV has become RFC 4791 now too.

Zimbra too

Zimbra is adding CalDAV support too: http://zimbra.svn.sourceforge.net/viewvc/zimbra/trunk/ZimbraServer/src/java/com/zimbra/cs/dav/caldav/

Bedework is getting there as well

Bedework is getting close to a CalDAV implementation and offer SyncML, web clients, etc.

Written for tomcat.

I appreciate RSCDS, but find

I appreciate RSCDS, but find it a bit restrictive to have to install and set up postgres in order to use it -- in this respect it is not "really simple". I might suggest making it possible also to use sqlite. I know this requires a bit more work, but then it would be a little closer to "simple", and easier for a more widespread audience to use it. In particular, I don't have a problem with using postgres, but the server I am wanting to run it on has 40megs of memory, and running postgres is simply not an option because of the other software already running on it.

PEAR goodness

why not use the PEAR:MDB2 wrapper and allow MySQL, PostgreSQL, SQLite and pretty much anything else out there? mysql support would be pretty nice...
