Multiple localizations on same RTC client

Hi,

We are setting a customer up with 3 different localization databases (DK, UK, US).
Some users need to access all three databases, and preferably using the RTC client.

What is best practice. Could we just install the DK RTC Client and make three shortcuts using the switch -settings:<clientusersettings.config> to connect to the different NAV services? Or must we install 3 different RTC clients, one for each localization?

Thanks.
