There is no problem as far as the SDL language is concerned. The environment
of an SDL system is expected to behave in an "SDL-like" way. The environment
of one system can therefore contain one or more other SDL systems.

Whether you can actually do this will depend on exactly what run-time system
you are using and how it is integrated with the SDL systems.
