I thought the repeated shots at Tom (there were two) over a commercial
interest were snide and uncalled for and, more importantly, were a
distraction from the point Tom was making. In addition to his
shareware (which is cheap, but even if it wasn't wouldn't be evil in
any event), he also provides some free products and wonderful support
(the few times I have availed myself of it). The discussion gained
nothing from the comments, but then it gains nothing from these either
and so I will let it rest there.

Me being sloppy, you are correct. For the record, it uses an embedded
version of dvipdfmx to convert dvi into pdf or, in extremus, dvipdf
using an external distiller. My experience is that the things I have
seen it bogged down by are exactly the same things that cause issues
for pdftex, specifically eps graphics. It may be argued that one
should simply convert the graphics to pdf, but why would you want to do
that if you are working with dvi to begin with?

Your assumption is again correct. Once the document has been conerted
to pdf TeXniscope is fabulous. Most of my experience, however, has
been in experimenting with synchronization between TeXniscope and Alpha
(Max and Joachim have done a great job). For non-trivial documents
TeXniscope can be simply unusable because the conversion is slow. One
consequence of this is that communication between the two programs
seemed to break down, although that may have been a consequence of my
impatience leading me to queue up a few instructions.

You were right both times :-)

I've never used xdvi, but I found MacDviX and OzTeX both *much* faster
at providing output that could be viewed from a dvi source containing
eps graphics, at least those I was working with (which were just papers
I hppened to be working on, there was nothing special about them). And
both provide at least reverse searching of documents (dvi to source).
As a final comment, let me reiterate that I think TeXniscope is
fantastic and it has tremendous potential. But even on a reasonably
quick machine (2.5Ghz G5) the internal conversion of dvi files to
something else can leave it at a very substantial speed disadvantage
relative to the dvi previewers that I compared it with.
