We've used R's sna package locally to generate lots (and lots, and lots, 
and lots...) of graph plots.  It works well, particularly for work with 
data that may not conform to people's initial expectations of what 
relations may be...

However... it is sometimes a bit memory-hungry.  :)  You are correct in 
asserting that you will need quite a bit of memory to plot a large network 
- I've used numerous 16GB and 32GB machines running Sun's Solaris to plot 
absurdly-sized networks with what I would call a good degree of success.

All of the standard tricks for working with large matrices work quite well 
with R-sna.  [In effect, there's a real payoff for properly trimming or 
partitioning your data as early in the analysis process as possible...] 
Getting to know the other R packages that deal with matrix-oriented data 
is also highly recommended, for those who want to make serious use of 
'sna'.  Several of the more useful tools are not actually *in* the sna 
package, but found inside other toolkits that are packaged for R.

A few of Katy Borner's students have simply run Pajek under Wine; that 
seems to work well enough.  I don't think I've seen anyone run UCINET 
under Wine, but I suppose that should also be possible.
