I'm a little confused as to the nature of single pass rendering versus
multi-pass rendering. What are the advantages to rendering in more than one
go (e.g. rendering radiosity, then loading the data and running the final
pass)? Aside from the paragraph explaining how to save and load radiosity
data, it seems the help file glossed over this information.

The initial passes are done with a smaller error_bound. Thus you
get (at least in theory) higher quality without having to have a
very small error_bound in the final pass.

You may also check http://www.nolights.de/projects/radiosity/radiosity.html,
where I've documented some Indoor-Tests with the Two-Pass Radiosity that was
developed in a thread on these newsgroups (that fine chap Gilles Tran
admitted it wasn't all his idea when I credited him on the page, so that's
why I know, I haven't witnessed the discussion itself).
Regards,
Tim

Thank you, that link is very informative. Now all I have to do is dedicate a
few hours to poring over it
