[OSM-talk] Osmosis error with multiple bouding boxes

[Lambertus]

Thanks for answering so quickly. I have had some advice on the IRC from TomH 
and Bobkare and others to use the tee utility with an adapted version of the 
planetosm-excerpt-area.pl script (that can handle stdin data). So far that 
seems to work alright (haven't seen the actual results yet though) but it 
looks promising. However, let that not stop you from implementing the tee 
functionality in Osmosis, because that would e.g. allow Windows users to 
have the same functionality. I might also change back to Osmosis when 
tee-ing is possible.

If you implement the tee functionality please allow for an 'unlimited' 
number of consumers as in my current setup I need already 150+ and that 
number can easilly grow :)

The pipe connection documentation is a little vague.  It doesn't quite
work that way.  Once a task reads a pipe, the pipe is consumed, multiple
tasks can't read the same pipe.

What you need is a new "tee" task that will allow you to send data to
two destination tasks.  Won't take much effort to write, just hasn't
been needed yet :-)  I'll try to knock it up over the next few hours.
