I am not a core developer of sesame, but I update their openrdf2
repository quite often.
 From my knowledge and what I know from some project members,
they work hard to get their file-backed SAIL implementation they had in
sesame1 out for sesame2.

Sesame2 has context/named graphs, which makes a lot things possible.
web interface still missing.

a good massive store is still RDFGateway (windows based, non-opensource)

We will play with sesame2 in about one week, when we make performance
stress-test for
which is about 100.000 to 1.000.000 triples.

We had very bad experience with jena, especially the normal DB-backend.
in the version I used they had something like this in the triple table:
s p o
uri:http://ssss ... literal:en:"asdfasfd"
so they did encode the difference between RDFNode/Liuteral/Resource
objects as parseable string.
sparql2sql is nice, but didn't solve our problems
