Agenda:

	1. Porting to OSX -RJ
	2. Detector Simulation Packages -SP
	3. HDDS proposal -RJ
	4. Barrel Calorimeter Simulations and Geometry  -EB
	5. Start/Vertex counter simulations -EB

1.
Richard reported success in compiling and running hdds programs on
OSX provided a gcc3.

2.
Snake, Transport, Garfield, MagBoltz, (P)Spice, ...

3.
Richard suggested implementing a gatekeeper structure for
making changes to the detector geometery definitions in 
the simulation.

4.
BCAL has grown into Cherenkov. 
Gatekeepers should eventually be used.
HDFast event display projections from 4-vectors which is
not necessarily the track MCFast used

5.
Vertex detector resolution does not seem to affect momentum resolution
and has relatively little affect on position resolution.
