How to map accounts & leads in the mobile application (Google / Bing / others)?

Hello Sugar lovers,

One of our customers would like to optimize his workforce productivity by facilitating meeting organisation on the go. Example: a salesperson finishes a meeting at a customer's premises and would like to see his nearby clients (accounts) or prospects (leads). I imagine a map of accounts/leads centered on the mobile phone's position. 

I'm aware of the wMap plugin but that does not work with the mobile application (requires wMobile) and might not meet the specific account filtering needs (via an intermediary module). We might use that module, though, since it does the geocoding pretty well. 

How would you approach that? I suspect that would require extending the app via the SDK? 

Cheers,

Damien
