Your fix makes me sound important until you stop to think about it!
Thanks for the good wishes. I certainly hope so too. I have nothing on the horizon right now, and I have to admit, I am very concerned about finding a job.

To put our car on jackstands we used the rear jacking point and put one jackstand under the front jacking point and the other (with the cradle removed) over the bolt head near that rear jack point that holds the black brace that runs at a 45 degree angle from there to the cross member. It's hard to describe from memory and without pictures but it should be pretty obvious. This method was much faster and much much safer than putting the front on stands and using the engine to lift the rear.
Just my 2 cents worth. I'm probably wrong.

You should try the cats. I think I saw a thread somewhere that someone used the cats to lift the engine due to some theory. It works! Why not?

I can't believe I'm doing this. My first post on a new forum and it may make enemies out of half the members.
The engine only hangs down about an inch. When you jack up the engine it goes up about an inch and then the engine carrier hits the bottom of the rear bumper structure. So the weight of the car is not on the rubber part of the mount, it's metal to metal. If the mounts are in good shape the rubber will just retract into the mount as the engine comes up.
If the mounts are worn and sagging and collapsed and hanging out of the mount, (and that is what they do) then I suspect when the engine is jacked up they don't retract and the bladder gets pinched. That's why they pop, burst, leak, explode, die.
I personally don't care about the mounts. If they pop they pop. I'll replace them.
What concerned me most was damaging the case. Could that little lug really support the weight of the car? Well I accidentally tested that. I jacked up the car with an old floor jack. The kind with a really deep cup style saddle. I didn't realize all of the weight of the car was on the thin edge of the saddle, and not even on the flat lug, on the bolt behind it. It put a little notch in the case but no cracks or damage. I definitely don't recommend trying that. I now use a pad.
I place jack stands directly in front of the factory jack points. None of my stands will fit on the jack points securely.

Careful with RHINO RAMPS.
Fast forward this utube video to around 2 minutes or so.

I always jacked my 1999 C2 from the engine when I needed to get both wheels and tires off the ground (i.e., to change plugs). I did not do it if I could get away with leaving the tires on (like changing the oil...I just lift one side, pull the plug, lower the car to let it drain while level, then raise one side again a bit to get access to the plug to re-install.
I had a motor mount pop one time while engine jacking. (the car had 80k miles). I spoke to my indie tech (who happens to be an ex porsche premier tech, and he said exactly what Orient Express says: it is not the act of jacking form the engine that busts the mount. If a mount fails in this circumstance it had already failed or failure was imminent. He frequently jacks from the engine if he wants to do something on a customer car quickly without getting the car on a lift.
By the way, when I bought my turbo I visited the evolution motorsports showroom and asked them about a safe engine jacking spot for the turbo...they pointed me to a spot on the case and indicated they frequently jack from there (but only long enough to get the stands under the stock jack points).
I think the absence of an official "engine jacking" location from Porsche is born more from a desire to force people to go to the dealer for repair/maintenance than anything else.
My two cents. I'll continue to engine jack when necessary (guess I'm foolish).
