Enterprise Manager

I would like to install multiple agents on the same host, to go against a single repository/oms on a different host.

For example:

Agent A is owned by user oracle and runs on port 1
Agent B is owned by user something_else and runs on port 2.

They both upload to the same repository.

I already now how to manipulate the emd.properties file to run the agent on whatever port I wish.

Is it possible or will there be conflicts because the host is the same?

Thanks.
