French synonyms & Online synonyms

[Pierre Auslaender]

Hello,

I'm sure these questions have been raised a million times, I'll try one 
more:

1/ Is there any general-purpose, free, French synonyms file out there?

2/ Is there a Solr or Lucene analyser class that could tap an on-line 
resource for synoynms at index-time? And by the same token, maintain and 
complete a synoynms text file?

Thanks for the great work on SOLR and for the liveliness of this list.

Pierre
