What do you mean by bluetooth-frwk ? bluetooth-service daemon ?
For the moment, bluetooth-service daemon can only run as 'app' user even
if 'bob' and 'alice' are using bluetooth (over C API).
So when 'bob' uses bluetooth over bluetooth-frwk, obex is run for 'app'
user instead of 'bob'.
> The reason is that obexd features is included in bluetooth-frwk and obexd only run on each user not root user.
Yes, I agree. May bluetooth-service could run as root and launch obexd
for different user.

As described in https://bugs.tizen.org/jira/browse/TC-1411, BlueZ is
currently not able to handle multi-user accesses.
For example, if user1 is paired with deviceA, we do not want that user2
is also paired with deviceA and access to user1 info.
We need to set up a multi-user policy in a daemon discussing with BlueZ.
As bluetooth-frwk is user specific, a central daemon can handle all of
the user requests and forward them or not to BlueZ.
