Let's not forget that installing SSIS on its own server requires purchasing separate licenses for SQL Server on that server. If you are running SSIS on an ETL server and do not have the licenses required - it could end up costing you a lot more than you realize.
We already have a license for our ETL server... which is what bemused me. The organisation I'm working for is relatively small and budget-conscious. It seemed like a luxury to have a dedicated ETL machine that pretty much sits idle for around 20-22 hours each day. Both in terms of under-utilised hardware and in terms of licencing costs.
