Compatibility with sql 2000

Can I Install Sql 2005 in a machine with sql 2000? Will I have problems when the final version of sql 2005 comes out?At RTM of SQL Server 2005 we will support installing it on a machine that already has SQL Server 2000 installed. We have put a lot of work in this area to insure they can install harmoniously on the same machine. We don't recommend installing SQL Server 2000 after SQL Server 2005 is already installed - but the reverse is okay.

Dan|||1. RTM is still a few months in the future, what about right now, will it break 2000?
2. If not, will it be OK if 2000 has Report Server installed?

Thanks.
