I have found Bob Wheelers Vade Mecum to be one the most useful tool I have in my bag for my photography. As we all know does not exist a version for the iphone / android phones etc. What I am proposing is a colabaration of individuals interested in seeing Bob's great program sponsor a reputable programmer to port Vade Mecum to these modern devices. I'm not certain about the legal detail and there is always money involved. However if the port can be done and there is a minimal cost then perhaps Bob could receive some royalty for his program. If only I were a programmer! Anyway what do you think.
