Well the proposal count for OSDC 07 seems to be at 99 (their web site is not very secure!)
Assuming eight papers a day (which is probably too many) in three streams plus keynotes they would appear to have more papers than they need -- which is very good news. Perhaps we will get a fourth stream?
I have not looked at how many of the 99 are tutorials, which take place on a fourth day so my numbers are slightly askew.
Wonder if I will be accepted...
