pelago: Unfortunately, I don't think that is possible at this time. Desktop widgets can be added one time only (unless I am missing something - please let me know if I am!) There are certain restrictions to desktop widgets - at least in the beta 2 SDK.

I can see the appeal of multiple instances, especially with the panaramic desktop area making it possible to group things how the user desires. If I find out that this can currently be done, or if it becomes possible to do it in the future, you can be sure I will implement it.
