Will Yahoo ever develop a messenger app to use in real time (not the use of the mobile web)?

Right now on most smartphone you have to use an app like beejive, Meebo, Nimbuzz, etc to use Yahoo as a real time data messenger application. Will Yahoo ever develop an app to use in real time instead of using the mobile web? for me, using the mobile web is quite an inconvenience in comparison to the various apps that are available. just curious and thank you in advance!
