I will give you this offlist as not all entities publicly are willing to admit 
to using free software.  Kind of silly huh.

This is correct.

GEAS development has been moving forward nicely over past few days.

If you let us know where forms is too limiting we might be able to help.

Just matter of bastardizing queries to get there.

Yes.  We plan to support leveling in this fashion.

Best I can tell this takes FO (formatted objects) and transforms it.  We plan 
to support FO.  Our model allows for pluggable components so you could even use 
FOP from apache if you so like to go from our FO to PDF.  I imagine if an 
FO->ps,pdf,etc isnt ready for python by the time we get there, that we will 
either use a java one until a python one becomes ready or consider converting a 
java one to python. :)
