Hi!
So you want to build an app that talks to the bitcoind / litecoind deamon? Very curious what plans you have.
If I may make a suggestion: when you want to lead the project from the architecture perspective I recommend a app like Pencil project (
http://pencil.evolus.vn ). It's an open source prototyping tool which let's you create mock ups for interfaces and also let's you draw out process flows.
These two can be shared and edited by the developers and this could aid in a broader understanding among developers on what was meant by certain comments or ideas. This could be important since communicating over the internet has some drawbacks which could result in the loss of some of the necessary context.
You can install Pencil on Linux using your favorite package manager. For Windows and Mac there is a download on their website and also there is a portable Windows version on PortableApps (

Maybe this will help you a bit.
