[R-sig-Geo] Current options for creating/querying vector data WITHOUT loading them into memory?

[Jonathan Greenberg]

r-sig-geo'ers:

As vector datasets are getting a lot larger, there is a limitation
with the Spatial* formats in that they must be loaded into main
memory.  I was curious what folks who have been dealing with massive
vector files have come up with working within the R environment?  Has
anyone played around with file geodatabases or spatialite formats (for
instance)?  How are you creating/querying the data?

Thanks!
