Calculator that generates results in table format

1. What Is It? – A Desktop application. Note: If you can make it to be installed on Mac and Windows, (Adobe Air?, Java?); I will see your proposal very favorably. 2. What Does It Need To Do? i. Accurate Calculation: The application needs to be able to generate a table of calculated values based on inputed numbers/values by the User. ii. Open new tabs (tabs like in firefox and chrome) for different calculation tasks. iii. Add all calculations subtotals in different tabs into a Final Total. iv. Export calculation results to CSV and Text. v. Support a registration system via licensing system for BASIC version and PRO version. vi. Restrict feature depending on versions and trial period. vii. Newly installed software have 30 day trial period and access to all features. After trial ends, usage is limited. 3. Misc: i. I own the source code to this project and all copyright ii. Code should be well commented iii. Be available for future updates and support (if needed) If you are interested, please add the word "Borneo Mocha" in your application and send in the NDA. After doing so, I will give detailed specs, wireframe and flowchart for programming. Please show me your portfolio of developing similar projects or help maintaning similar projects.
