Is Exporting, Importing objects from or to Secondlife and Opensim possible.
Yes a few applications work either way, how useful that is, is depending on what you are exporting or importing.
SecondInventory will import and export (backup)most items, a few 3rd party viewers will attempt to do the same in some sort of a fashion.

The flow of content as expected is from SL in to other grids, mainly because SL “has it” and the the other grids are new and looking of content. This is changing with lot of content being made in opensim based grids right now.
When we first started in Opensim our aim was to take what we had in SL and transfer it to Opensim. This was painful, lots of imports got screwed up and lots of time was lost in cleaning up. That was more than 1 year ago and things have improved. With hindsight we should have rebuilt and made a fresh start.
Using Opensim as your workshop (developing platform)) and exporting your product in to SL sounds like a good idea and it can work.
However if you use lots of large building blocks (prims larger than 10×10x10) as you do in large buildings it gets hard if not impossible to export to SL (max prim size in Sl is 10 x10 x10).
This stops a lot of design flowing from Opensim to SL . On the other hand importing a build from Sl containing lots of prims that could be built with far less in opensim is also not a good idea.
Conclusion: As a first step SL should change and allow building with larger prims!
SL has far more users and content. Removing the wall and have free trade will benefit all ( free trade removing trade barriers I have heard this before…). The platform is sound it is inexpensive and relatively easy to learn, that can benefit everyone from large cooperations, governments to individuals.
OpenSim supports: Large prims, Hypergrid, Megaregions and Oar backups that alone makes it an advanced and professional 3D simulator.
