There are two issues:
1. Allowing an author using non-W3C technologies to claim conformance to 
WCAG 2.0
2. Publishing techniques for non-W3C technologies

WRT 1 - We encourage authors to make accessible content and we encourage 
technology developers to build accessibility features into their 
technology.  If a technology can be used to meet WCAG 2.0, it should not 
matter who designed the technology.

WRT 2 -  Because we are a vendor-neutral organization, the W3C/WAI will 
only publish techniques for open specifications that are produced by a 
consortium.  The scope of our charter says, "Develop techniques for 
implementing the WCAG 2.0 in W3C Recommendations (such as XHTML, SMIL, SVG, 
and MathML) as well as ECMAScript." [1] The WCAG WG is not likely to 
address *all* W3C technologies and we encourage other W3C Working Groups to 
write authoring techniques for their specifications (some groups have 
expressed interest in doing this).  The WCAG WG (in coordination with the 
I18N WG) provides a schema, data and transformations [2] that may be used 
to produce techniques documents. It is my understanding that Adobe and 
Macromedia plan to publish techniques documents for PDF and Flash
