No there is no connection possible with the v6 client (yet)
and as far as i know SBC is replacing the whole concept of SBS suite.
the so called connector, to connect v6 clients to ADNM, i have heard of is not coming out for a while as far as i gathered...
Sinds the SBS 2011 version is really server 2008, it should work... Scythe is more at home in SBS servers tho...
