Sync NIS-IDSafe .npm?

I see no obvious news on this front - multiple PCs, single identiy, can one use (say) WinLivSync peer2peer connection to keep 2PCs/1user Identity Safe in sync?  (If not, why not?  I use identical login on multiple machines... a shame to delegate the task to insecure Xmarks when NIS-IDS is at one's fingertips)

Has Symantic it's own cloud/sync service for this sort of thing?

 

Thanks
