I agree with Jon. Let's make the target SE. Anyone who can afford $100K versus $20K can afford to create bitmap indicies on their own where needed.
There really aren't that many EE-specific features used in ACS 4/Tcl. Back in February I posted a list of http://www.arsdigita.com/bboard/q-and-a-fetch-msg?msg%5fid=000Yx2&topic%5fid=ACS%20Design&topic= (tweaks to the ACS 4.1 datamodel) that we needed to get it to load cleanly into SE. Both Don and Bruno Mattarllo asked in that thread if anyone at aD had ever done any testing. My guess is aD's silence means that no one ever did. Had aD just not up and walked away from ACS 4 Tcl I suspect there would have been more EE specific features used going forward. (Which would have been their perogative since they said all along you needed EE...)
