The main problem I see here is, that it is not very well supported.
Especially IE below 8 does not support it at all and IE8 seems to
support data URIs in CSS style sheets, only.
 
Quote from https://developer.mozilla.org/en/data_URIs (Common
problems):

"The data scheme is supported by Opera 7.20 and above, as well as
Safari and Konqueror. Internet Explorer 7 and below, however, do not
currently support it. Internet Explorer 8 and above only supports data
URIs for images in CSS."

Moreover this technique is somewhat problematic because it defeats
some caching mechanism, and will enlarge the resulting page -- not
very kind for people with small bandwith and/or paying by traffic.

I think something supporting this could go to hacks or contrib with a
big red warning about the consequences and a careful discussion of
when to use this and when best not to use it.

Best,

that lets you test your browser for the support of content included in
data URIs.
