Well now, here's a thing.
I emailed
Cycling 74 to ask about MaxMSP (since the version I had, which was 4.3, was failing to even install on my new laptop) and they replied that my licence covered me to download up to 4.6.3! Amazed and gratified I am!
Haven't had a chance to find out what it can do yet, but if this new bundle doesn't include Jitter, I think I want it. Might look into the price of an upgrade to the latest version... Eventually.
Isn't it nice when a company actually goes out of their way to serve their customers?
Just have to hope for the best that FontLab do the same with TypeTool...
