[igraph] iGraph noob - network size and memory

Hi all,

I'm new to iGraph, and to network analysis itself. I'm a programmer,
working on a network analysis project with a researcher. We're
evalutating what tools we might use, and R with iGraph looks
interesting. Initially we'll be working on graphs with millions of nodes
and edges, and possibly going up to hundreds of millions. The iGraph's
description mentions working very efficiently with millions of edges.
Does this extend to 10's or 100's of millions?

I've poked around a bit and seen some posts that suggest iGraph keeps
its network data structure in main memory. Is that correct? Did
something come of the suggestion to work on a branch with a (presumably)
disk-based database for the graph data?

Thanks for any answers. I'm looking around quickly at various options at
this point to get some initial answers for next week, sorry that I
haven't researched in depth yet.
