Dear Charles and all on list,
Sorry for the slightly hazy question that I put to the list. I am sadly not a technical person, more of an accessibility messenger! The following is more of a technical answer and may well help (although it could also hinder) those answering my question, or wondering how to answer it! <grin>

Font Streaming is, in this context:
When a user visits a site, a font type is streamed to the browser so that all text is rendered on that site in that particular font. When the user leaves the site, they also lose the ability to have that font in any other website. 

So, if I was wanting to use Verdana and it was not available as a Web font, I could stream that font to the browser so that all text would be rendered in Verdana. When I leave that site, my font becomes, say, Times New Roman/Helvetica/Arial because they are Web-friendly fonts that all browsers can display.

This only works in Netscape and Internet Explorer, no other browsers, can it can be turned off by the user in their browser and would be overridden by a user's style sheet.

I hope that this makes the issue clear and sorry for the earlier hazy post. In response to Charles directly, is this an issue for CSS2 and SVG or is it something that *should* not impact on the accessibility of a site?

Thanks everyone in advance, I fully appreciate everyone's hard work on answering these questions.

Kind regards

Simon

Hi Simon,

I am not sure what you mean by font streaming but if it is something like
webfonts in CSS2 or the SVG font system then there is some experience with it
(more so in SVG)...

cheers

  Dear All,

  I have a client that wants to use images to make the text look good on a
  Web page (because it is anti-aliased and that makes the text clearer) but
  this causes enormous problems that I don't need to mention here.

  A workaround for this would be the use of font streaming to control the
  look of the text. However, although I cannot see that this would pose any
  accessibility problems per se, does anyone have any previous experience
  of font streaming and accessibility?

  In particular, does anyone at the W3C have any further information on
  this subject? If not, I am going to trial the idea and see what happens
  and would be happy to share my findings with everyone as long as I am not
  duplicating previous postings or ideas.

  I shall leave this in everyone's capable hands and look forward to
  hearing what people have to say about it.

  Kind regards

  Simon
