Adding buttons to the mobile client record view?

We have implemented integration functionalities (such as sending SMS messages via third party services) in record view buttons based on  http://support.sugarcrm.com/02_Documentation/04_Sugar_Developer/Sugar_Developer_Guide_7.6/20_UI_Model/30_Views/Examples/Adding_Buttons_to_the_Record_View/ which works fine in the desktop client (7.5 Professional).

Now however, a customer would like the same functionality into the mobile client and at least so far I haven't managed to google anything useful about where and how a similar launch button could be added to a module in the mobile client.

I haven't worked with the mobile clients much so far, looking at the interface I don't see any obvious places where such buttons might go, and googling hasn't so far yielded anything I would have found useful. 

Is this possible or practical? If anyone has implemented similar API call buttons to the mobile interface, please share how you've done it.
