Yes

Well, I'm no Globus expert either, but as I understand it VOMS is one of the 
options you have in Globus (but it is not required at all).
See http://www.globus.org/grid_software/security/ in section "Components for 
Access Control and Authorization".

As I understand it VOMS is something that might be used with BDII as well as 
with MDS4 (although I'm not yet 100% sure how the VO mapping to resources 
works there - I got dumps of some GT4.0 MDS servers where I can see some 
pattern, but thats something to investigate further). 
The binding of a info system type to a VO type that we have right now in g-
Eclipse now might be to strict. You are right - that is something to discuss 
about, especially since this means touching stuff that is completely in the 
core of g-Eclipse.
