wait a second ...
if you have an index you can probably do it with 1 seek assuming you have
the index loaded, without an index it will be log n seeks anyway so IMHO
1 extra isnt a issue, the complexity of my suggestion might be an issue
though
IMHO just add backptrs with stream groups or 1 backptr for every stream
and forget about it, people who store 100 streams dont care about overhead
anyway
