Subversion does internal diffs identically, whether it's a binary or
text file. The difference comes in when you want to *review* the diffs
- you can't do it without extra tools that are specific to that

It is a good idea to give Subversion, other software, and other
people, an indication of what the filetype is via the svn:mime-type

The current release of Subversion has no built-in ability to run
scripts upon checkout. What Ryan was getting at is that rather than
keep binaries (which tend to be larger than their sources, and can't
be visually diffed easily) in the repository, one usually only keeps
the means by which to produce those files in the repository (the
source and the build script). So your workflow would be:

1) Checkout/update
2) Run LaTeX to PDF script
3) Do whatever with the PDFs.

You could also write your own wrapper to do the checkout or update,
then run the script automatically.

To answer your later question, yes you can change protocol as well as the URL.
