64 bit *is* the future, data is getting bigger all the time, even PC's can accomodate come with 4GB+ memory, soon it'll be that standard machines will come with that much memory, let alone just our high end graphics machines. I don't think its much of an issue of "if" you do a transition to 64bit, but "when", as software engineers we have to write code that pre-dates when our users move on mass across. The OSG has supported 64bit for many years as users required it (oil and gas developers were the ones at the bleeding edge), I've personally been using 64bit linux as my main platform for the past 3 years. I do have an old laptop that can only do 32bit, so its good to drop down again occasionally, but to be honest you don't notice any difference going between the two -its only when you stick plenty of memory in a machine might you notice a difference, and that's pretty well the way it should be.
