Since you seem to have limited options, I'll offer a few others.
How about archiving the files with something that preserves
the file attributes ? zip format perhaps ?
Of course, you would have to have a scheduled job running
on the webservers to unravel the zip file when it appears.
Snippets of code should be wrapped in
<code> tags not<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
