The bandwidth alone required for that to happen would never work. Your best bet is to create small proxies for editorial and send those via dropbox, WeTransfer, or other shared/send file solutions. If duplicate media exists in both areas and is managed by Avid, it is easy to send bins/sequences back and forth during editorial.
Avid does provide for an Avid Everywhere with editorial over browser, but requires ISIS storage, Interplay, then additional options on top of that to make it work. You’re talking 6 figures to get that working.
