In a master project, the subprojects do not need to have the same Owner.
And you don't even need to build a team in the master project since each
subproject has its own team members.
I don't really think there any "gotchas" when using a master project. To
create a master project, the user must have permissions to open and edit
each subproject, and must have permission to view all the resources in all
of the subprojects. In a very locked down environment, that could present
issues. On the other hand, the nice things about master projects in Project
Server 2007 are:
1. Executives can select the master project in the Project Center view and
then expand the subprojects in the Detailed Project view.
2. You can safely publish a master project without doubling the resource
assignments (a problem in 2003).
3. When you publish a master project, the system automatically publishes
all subprojects as well.
4. You can create subworkspaces for each subproject under a single master
project workspace.
5. You can set up navigation tabs in the master project's workspace for
each subworkspace. To do this, refer to the following FAQ and Blog:

Hope this helps.
