"not easy" is an understatement!  I've played around with
a couple of these once.  They seem to be very complicated
unless your a 5250 data stream expert :)

Is this the method that Webfacing uses?  If so, do you know
how long it took the IBM programmers to write that package? 

Even with plenty of in-house expertise, I'll bet it took
quite a while.  Not something your going to whip out in a
