Using Teradata host for both database and ETL?

When working with Teradata I have always used one host (mainframe or midrange) to control ETL and the teradata database was isolated on its own hardware where nothing else was running. Has anyone worked with ETL processes that actually run on the Teradata host itself? Is there a good white paper that talks about this and the pitfalls?

Thanks!
