I know this is an old article, but it sounds like exactly what I have been looking for. Is there any reason this would not work using SQL Server 2008 R2?
Nearly 3 years since the last comment, yeah, old..
1. IIS is not needed for SSRS as of SQL 2008 (and R2)
2. This is considered a scale-out deployment and is only supported on Enterprise Edition as far as I know.
3. As the last poster commented as a question about licensing, both nodes would have to be licensed, which would not be an issue in the Active/Active case since you would need to license both anyway.
4. Technically SSRS is not cluster aware so it will not failover in any traditional sense. You are really only effectively running two copies.
