Can't make it but wish I could.
Will be there next week for sure.

Also I was on the open source ecology conference call yesterday about a True Fans platform and mentioned what I knew of the OMI efforts to make the compressed earth brick press, see here:

I plan to continue liaising in these which are planned to be bi-weekly; perhaps y'all would like to join.
