Invite preexisting accounts to manage - OR Multi-Vendor Access via multiple streamers
Instead of having the client juggle email account instances for separating the accounts, have the programmers allow us to run multiple instances of the streamer. (instance1 mine, instance2 bookkeeper)
(I'm assuming its not already done yet based on how the objects are being handled internally.
So till we can figure out that data to sift through and convert into individual objects that can be cross linked to a vendor and an encryption token, or whatever, we can resolve it externally. This would give the appearance we are looking for from an IT management perspective., and nothing really had to change internally to how your data moves around.)
