iPhone PTT - NikoTalkie

Now iPhone has its VoIP application ready. It's called "nikotalkie" and works like a walkie-talkie or any other PTT (Push To Talk) software.

Now what I am wondering is:

• Is there a plan to make it work on other phones OSes, like Symbian (it makes me think of Nokia E65, for instance)?
• Is there a Utility in walkie talkie feature "as is"? How many people have PTT installed? How many do use it?
  
• Is there some plan to extend the "walkie" function like, uh, ya know, mobile micro-video-blogging?
  
• is it complicated to install the iPhone "installer"? It seems it is not that straight
