On a phone, the OPR/DPR calculations will eat up battery life as if there weren't enough LiPo cells in the universe. Thus, this information is best calculated on a server and fed to the clients. I've experimented with just such a program that does OPR/DPR based off of the live frcfms Twitter feed for IRI, and the results weren't pretty.

Since I used Java on a my jailbroken iPhone, I should be able to do some rewrites for use on a Netbook; however battery life and internet connections are still a concern.
