I port the plugin to VisualSmalltalk and we have it working well (not heavily tested) for half a year.
I could help on this project on the plugin part (for windows and unix only) and on the image side. The problem is that i'm going on vacaction on next weeks so i shall participate only since mid-June. Also i have not too much free time. Anyway i will be interested on using and testing it.
