I'm considering impersonation a purely technical approach, as you're largely indistinguishable from the impersonated user account.

My recommendation would rather be to utilize accounts for this purpose.You can share a cart within an account.

Could you provide more detail on the use-case?  If these are two people that work for the same company (Account) and are sharing a cart then you would want to ensure you have set up your Channel as B2B or B2X and use Accounts as Olaf has suggested.  

However, if this is a customer service agent or sales agent that's helping a consumer (B2C or B2B) then you would want to look into setting up a Sales Network.  There is some documentation here:  https://learn.liferay.com/commerce/latest/en/users-and-accounts/account-management/using-organizations-to-create-a-sales-network.html that might help you.  You will need to create Organizations to model the "seller" and Accounts to model the "buyer" and define a Sales Agent role as desribed here;  https://learn.liferay.com/commerce/latest/en/users-and-accounts/roles-and-permissions/commerce-roles-reference.html?highlight=sales%20agent#sales-agent. 

i'm trying to post.. and it isnt getting posted.. is there a glitch in the forum?
