What are the "URL length limitations imposed by user agents"?
A quick search does not show any hard limits outside of IE's ~2k
limit. Presumably
IE could be convinced to increase that for data URLs.

If the answer is 2k, then toDataURI is useless in practice and should be
dropped from the spec, even if we don't replace it with something else. If
the answer is 1GB, then at least it will be useful for the vast majority of
use cases (i.e. pictures, youtube-sized videos, etc).

Do we have any of this data for Gecko, Opera, WebKit?
