The DSR and DAI <---> xDAI

With DAI needing to be placed into the DSR contract (post both MCD launch and DSR launch), how will xDAI function then? I suppose DAI placed into the bridge contract could also be locked in the DSR as well. Has anyone explored this?

Are you asking if there is a mechanism for dai being locked in multiple contracts at the same time?
This seems to be in contradiction with the locking concept.
I understand how ethereum works only superficially, but i doubt you could do this without creating a new (proxy) contract. Basically makerdao and bridge contract creators would need to cooperate.
