That's interesting because I really knew of the work by Shneiderman and
Perer (http://www.cs.umd.edu/hcil/socialaction/) to build a new SNA
analysis and visualization tool.  Adam demonstrated it for us but I
guess it hasn't been released yet. You all may have seen it demonstrated
at SUNBELT or maybe INFOVIS 2006?

Title: Network visualization by semantic substrates

Abstract:
Networks have remained a challenge for information visualization
designers because of the complex issues of node and link layout coupled
with the rich set of tasks that users present. This paper offers a
strategy based on two principles: (1) layouts are based on user-defined
semantic substrates, which are non-overlapping regions in which node
placement is based on node attributes, (2) users interactively adjust
sliders to control link visibility to limit clutter and thus ensure
comprehensibility of source and destination. Scalability is further
facilitated by user control of which nodes are visible. We illustrate
our semantic substrates approach as implemented in NVSS 1.0 with legal
precedent data for up to 1122 court cases in three regions with 7645
legal citations.
