Can I have a page that fills up the memory on your machine and takes a
long time to download a lot of images?

Yes.

Has this been a real problem?

No.

If I install Ascender's "Liberation Sans," but a website modifies it
and references it with @font-face also as "Liberation Sans," I will
want to see the modified version in the page.

If I use the UA "install font" functionality, the UA will have to ask
me to rename the font (and have to go into the font's internal data
structures to do so.)

The HTTP server sending MD5 sums of its font and the UA making MD5
sums of installed fonts might work to speed things up, but might be
too fragile.
