Structural Biology Grid

In crystallography, updating software and general system maintenance can be quite time consuming. The Structural Biology Grid (SBGrid) was developed to help combat that issue. The SBGrid is currently comprised of 131 laboratories throughout the world. The SBGRid maintains a complete installation of structural biology applications complied and optimized to run on OS X (PPC and Intel), Linux and SGI. SBGrid has an extensive list of crystallographic software.
To become a member you need to contact them for details.
This program could be a real benefit to crystallographers that do not have a background in system administration. Unfortunately, the requirements of joining are not described on their website so am not going to get too excited.
If you are an affiliate of SBGrid, I would love to hear about your experiences.
What do you think about SBGrid? Could this type of program benefit your lab? Do you think this type of setup maybe the future for most crystallography labs?
