How big are u-forms currently?

MAYA Viz estimates that 98% of u-forms in the CPOF application are under two kilobytes in size. However, we have, on occasion, created much larger u-forms (up to at least 200 megabytes in size).

One could imagine, for instance, storing a feature length film MPEG-2 stream in a u-form and thus requiring an attribute value size around seven gigabytes. Current technology would not handle this well.
