Other spatial database development (PostGIS)

[Mike Davis]

Since we seem to be building some momentum on the ESRI personal
geodatabase thing, it seems like a good time to bring up the other
database related item on our wishlist.

What would be required to allow read/write to a PostGIS database from
ArcGIS?  I would love the ability to maintain our spatial data in
multiple datbase formats (must me my irrational fear of vendor
lock-in), but unless we can manage the data from within ArcGIS it
isn't really a practical option for us.
