•This is not without it’s problems

•csTCDie on LCG2 and Grid-Ireland, no Multi VO

support in R-GMA, but expected later.

•Grid-Ireland has helped enhance software

•Routing Queue, Heterogeneity - Fedora, IRIX,

AIX

• Info-Provider problems, accounting(?)

•Transition to Quattor/SL3

•Still yet an unknown, test on TestGrid
