How we can create multiple login session under single apiclientid?

[brianlai]

May I know for current api, will it support multiple login session under single apiclientid?

I tried to call in various method to the api, but after logged in to vB using user.login, the apiclientid in apiclient table is bounded to that user id. Even if I use another user to login within the same clientid, it will override the pervious logged in session. It seems it is different with the standard OAUTH authentication

so I would like to know
1. apiclientid is 1:1 mapping with session (i.e sessionhash)?
2. If not, how we can init the api so we can have concurrent session under the same apiclientid? (ApiAccessToken or Secret are different is okay)

Very appreciate with your feedback. Thanks
