First let me say that I agree to Aaaron regarding his comment on
security respective privacy concerns.

Of course this is possible. If your're unique id follows a syntax,
which no other directory has, you can use the Apache directives Alias
or AliasMatch from mod_alias (a default compiled in apache standard
module). Or you use mod_rewrite (a non-default apache standard
module), if it's a little bit trickier or if you want to check if
those unique id directory which is requested really exists.

Do something like

  AliasMatch /subdir/(regexp-for-uniquedir)/page.epl /path/to/htdocs/subdir/page.epl

This should be similiar to the often used vice versa case, where files
are aliased into a lot of non-existing (short said virtual)

In mod_rewrite this should look something like this (the second line
gets evaluated first!):

  # Only remap file if directory exists,
  RewriteCond /path/to/htdocs/$1$2 -d

  # Only remap file if file exists,
  RewriteCond /path/to/htdocs/$1page.epl -f

  # Remap page.epl to ../page.epl in uniqui-id-directories
  RewriteRule ^/(subdir/)(regexp-for-uniquedir)/page\.epl(?.*)?$ /$1page.epl$3

(Untested, so no guaranties... :-)
