Record live Arduino variable data into Excel, CSV, XML files no PC programming necessary.

This video shows you how to record live Arduino data into a PC file.
On the Arduino side you need 8 lines of code to setup communication and 1 line of code per variable you want to manage.
On the PC side you use a tool named WawiLib-PC (Watch Window Library) that takes care of all communications for you. Serial, Softserial, USB, Ethernet and Wi-Fi are supported interface types.
The tool can also be used to read and write Arduino variables as you were changing the cells in an Excel worksheet.
WawiLib can create a separate file (with time stamp in its file name) each 15 minutes, hour or day, so long term recording is possible.
Data can be recorded time based or change based. Change based means that when WawiLib sees that 1 or more of the variables (selectable) change, it writes a set of all values associated with the current data recorder to file.
Multiple data recorders with multiple parameters can be active at the same time.
Multiple Arduino boards can be connected at the same time.
WawiLib can manage disk space so it can clean up the oldest (time stamped) file making sure your PC does not end up with disk space problems.

How about other micro-controllers such as Teensy?
Is this compatible? if not, how implementation is achieved?
