I wrote an application like this, for some years ago. From what I remember, 
there was a small but noticeable delay when communicating with the Erlang 
process. Pipes in Windows are a little sluggish (or were, don't know about 
XP or similar).

With todays faster machines, there's probably no catch. Possibly still 
slower than communicating with beam.dll directly, but my guess is that it 
would be good enough.

I didn't go on with it because I seldom use werl anyway, so other projects 
felt more important.
