Notes on a USB Key – Chapter 2

I changed the code for my project “Wendy” once again. In the former version of nstart.exe, the file had to be copied to the Notes executable directory.

This is no longer necessary now; you can copy nstart.exe to i.e the “root” directory of your USB key, regardless of where your Notes Client is installed. nstart.exe locates the notes.ini and notes.exe, makes the necessary changes and starts the client.

This is NOT project “WANDA”, IBM announced at Lotusphere2006. It is my solution on how to put a Notes client “installation” on a USB key. But I’m eager to see what IBM’s solution will look like.

Does anyone have some information about project “WANDA” ?
