Maemo application cannot be "just put in Mer repo" because they need to be built in OpenSUSE Build Service and Maemo application sources are full of Scratchbox surprises (See: http://wiki.maemo.org/Mer/Build for the build info) Once Maemo application is modified to support Mer, it will appear in the Application Manager (When, is of course depending on the developer of each app, or Mer developer who wants to have that app)
