Inventing a new microsyntax is tricky.
- "comma separated" implies you'll need to escape a comma when it appears in a URI; this may be a problem when the URI scheme assigns a special meaning to the comma (so it doesn't affect HTTP but still...)

Indeed.

Edward did not write it all as a spec, though, so cases like that might be a bit detailed for a first proposal. Hixies extension of srcset does however have some spec text, and that does in fact handle your first case:

<http://www.whatwg.org/specs/web-apps/current-work/multipage/embedded-content-1.html#processing-the-image-candidates>

- separating URIs from parameters with whitespace implies that the URIs are valid (in that they do not contain whitespace themselves); I personally have no problem with that, but it should be kept in mind

Me neither. I'm no big fan of non-valid URIs. :-)
