If it's significantly faster to do what you want in Flash, do it that way first. Your users are almost certain to have it. Most of the conversations of the evilness of flash are limited to the HN sort of audience. I don't think that the internet audience at large really cares about it all that much. If the features end up being really useful and you decide you hate Flash, you can revisit it and write it in something else later. If the features end up not getting used, then you saved yourself a bunch of time on a feature that didn't end up being a big deal.
