What about ${SCALE} or <VendorOption name="scale"/> ?

Hi,
is it possible to realize a scale-dependant font-size in
SLD-TextSymbolizer with geoserver?
I'd like to have some text, wich dimension remain still the same in
all scales on the map.As I know there is no SLD-specific way to achieve this. (Besides using
filters with scaledenominators, but this is not applicably for me).
Therefore I am looking for some vendor-specific option in geoserver to
do something like this:<TextSymbolizer>
...
<Font>
...
<CssParameter name="font-size">
<ogc:Div>
<ogc:Literal>2.3</ogc:Literal>
<ogc:PropertyName>$SCALE</ogc:PropertyName>
</ogc:Div>
</CssParameter>
</Font>
...
</TextSymbolizer>
Unfortunately there is no such a thing in our current implementation.
SE 1.1 has the notion of sizes specified in ground units... but it would take significant effort for us to support it (new sld parser/encoder needed, changes in the renderer to handle all the new features... wondering if there is anyone interested in the endeavour, or if we should start a bounty to gather enough sponsorship to do the job).
Having the current scale available as a generic property is possible thought, it's just very problematic to specify it in a way that won't clash with any existing feature attribute... any bright ideas?
Cheers
Andrea
