Copy Tiger Classic Support into Leopard Possible?

Question

I tried asking this in Leopard's pre-release forum and the responses were, shall we say "less than helpful."
Before you answer (noting that this is the "Classic Environment" discussion group), I am well aware OS 9 is dead (duh), I have an expensive CAD program that I would have to take out a small business loan to upgrade to the current, OS X compatible, version. Classic is the answer I can afford right now. The business loan will come in the future when I upgrade to a Macintel (my PowerBook can handle everything I throw it, thank you very much, and doesn't need replacing).
Please don't tell how dead OS 9 is and how I should move on (I have, with the only this exception). It is insulting to me and a waste of time for you. Please don't tell me about rebooting into a Tiger partition, I already know about this and it is inconvenient for my work flow. This is also not a discussion on the relative merits of Leopard over Tiger or Apple's decision making process.
On to my question: Is it possible to copy the TruBlueEnvironme (I'm not talking about the OS 9 system folder, that's just drag and drop), blued(?) and it's associated PreferencePanes, Menu Extras, etc. from Tiger into Leopard and have Classic work? Or did Apple do something else behind the scenes at the kernel/UNIX level that makes this impossible?
Thanks in advance (and for staying on topic).

Answer 1

Unfortunately no. Low cost CAD software is so crude as to be unusable.
"Engineering" software lives in it's own special "reality." If you haven't worked with software in this area you'd probably be surprised to learn engineering software costs between 4x to 10x the amount of software in any other area costs with equivalent level of technology or sophistication. The excuse is always that the end users has more to gain financially when they use engineering software over other types of software. Which, of course, doesn't hold up when you consider that advertising firms can make tens of millions of dollars making an ad campaign using Photoshop. Using low cost CAD software is kinda like using textedit to do a sophisticated, high end layout that would normally only be done in InDesign.
The CAD software in question is extremely well done and very Mac friendly (and I still recommend it others). It started off a Mac app from a small, family run business. It was so good, it became the standard for "low cost" architectural software (on any platform). At the time Apple (and this CAD company) switched to OS X, they got bought by a German company that sold very expensive architectural software. When they took over, the price went from $495 to $795 (depending on the packages you bought) with $50 to $100 upgrades, to $1200 to $2000, per seat (unlike "standard" apps, you can't use one license on both your desktop and your laptop) with $445 upgrades (and then, only from the immediately proceeding version). In our two man, family run business, that would cost us $2900 to get "two seats" with the same functionality as we have now.
P.S. To get a feel for the weird little world engineers live in: I went to a sales seminar for a new Windows engineering software package that did 3D modeling back in 1995. The one feature that totally blew away the engineers (and the sales team for that matter) wasn't the photo-realism of the renderings, the ease with which the models could be produced, or the rendering speed; it was the fact that you could copy and pasted data and images between programs in the suite. 11 years behind the times and they charged an arm a leg for it.
