Hi,
I have to administer a team that works with visual studio and eclipse in the same time. Some of the source files are used from both IDE’s. So I try to find a good way to use both tool together. I see several ways to handle with this situation:

1)    Use the same sandbox:
If I use the same sandbox from box IDE’s there are some strange situations. For example if I start the visual studio first, then I can’t connect to this sandbox with the eclipse client cause of the jazzlog. But If I start Eclipse first it’s almost possible (Sometimes I must start VS twice).
2)    Use two sandboxes with the same repository workspace
The Problem with two sandboxes with the same repository workspace is, that after checkin the changeset the other sandbox is out of sync, so I think this is no option
3)    Working with two sandboxes and two repository workspaces.
This solution is very circuitous. If I want to accept the changes from the other repository workspace I have to deliver the changes to the stream or defining flow targets between repository workspaces. Both options are very complicated.

So, for us it is a business need that the two tools work together, because we have some sources and generated files, which we need in both IDEs. So what are the best practices for that? And what are there knows risks and limitations for option 1?
