Scientific Word supports the same sort of thing, doesnt it?

at the \special level, true. but at the package level, you can just
use hyperref, which has drivers for dvips, dvipsone, dviwindo,
hypertex, and pdftex.

until Fabrice Popineau manages to finish the port of xdvi to Windows
that he is working on, perhaps.

my *personal* feeling is that using dvi as the interchange file is
pretty much doomed anyway. pdf has all the advantages, and few disadvantages
(the only one is size, really).
