Two or more vaults... data access between them

Hi everybody

We are moving to Solidworks 2011 and EPDM 2011, as being purchase by another company whom have had Solidworks and EPDM for about 18 months, at the moment

we have two main vaults on a server about 800km's away and a second server ( archive I think ) with the two vaults which are replicated back to the main server

Question is can you share data between the vaults, or is there a work around... as in the future we could be working on a product together.... or is the answer to decided who's vault the work will be done in and for one of the parties to login to the other's vault and work within their's ?   Or how would you do it ?

Also are you able to make/install a test vault on an archive server, without it showing on the main server ?

Many Thanks  Don
