While I cannot find the link anymore, I do know that there was a limit on how much money a company could make and still be part of the support system in LACLEANTECH.  This is a good thing!  EWSI is going to do 15 - 20M gross this year. 

No worries at all.  SURF is in a bigger location now.  They still attended the last conference.  I'm sure the doors are still open for these types of conferences, just not the free office space provided to brand new start ups.
