We tried out the broadcast feature with two computers and we ran into a few bugs. The shape recognition did not work on one of the Inkodo boards (only broken while in broadcast mode) and on the other board, the shapes that were recognized were not transmitted to the first board. We also had a problem with the "Erase all ink" function while in broadcast mode. The ink would not erase on the other board and as soon as something else was drawn, all of the erased ink would return. Similarly shapes that were deleted on one board would not delete on the other board and would return with the next addition.
As an aside, I'm not sure if this is fixable but handwriting recognition does not recognize o's when shape recognition is on since they are made into objects rather than inks.
