I described the use of ram_file_io_server in this post:

http://www.erlang.org/pipermail/erlang-questions/2006-July/021348.html

To which you suggested using a string_io module, which would
of course work too. One could say that a ram file is just 
another type of io device that, in addition to supporting 
the io library, also supports file i/o (not that epp really 
needs that).
