Load a component from different streams to same sandbox

We have a number of components under a shared stream. Recently we have 'branched' this stream to a new version, and we want to parallel develop the two streams. When we go to load the new stream (with the old stream still loaded), Eclipse has a wobbly because the Eclipse projects are named after the components (which are the same in both streams). It tries to load the Eclipse project, but fails complaining that the project is already loaded. 

what's the best way to get around this so that we can have the two streams loaded in the same sandbox at the same time (but to different sub-folders)?

Thanks
