what i meant was that epp should accept an IO device (as returned from 
file:open/2), too. this seemed a good idea since it probably used one 
it is easy (since i have done it :-) to write your own server that 
handles the IO device.

if i understand you correctly then epp does not use the io module 
internally but have opened in raw mode. correct?

then it is a large (but trivial?) undertaking to change epp from 
file:read() to io:fread().

that is ok too. i have not done it, but it could be more fun than 
changing epp to use the io module.
