just a thought:

As probably only very few properties need to be UA specific it may be 
easier (to author and maintain) to different on the property level and 
not the rule or even @media level:

div {
     width and gecko: 80px;
     width: 100px;
}

so like the syntax for MediaQuery, or maybe even

     width[css:ua="Trident"]: 80px

with an XPath like predicate syntax. I guess the actual syntax is not 
the problem but where these things should be placed in the first place
