Being ignorant about such things, I copied tclAE2.0 into 
/System/Library/Frameworks/Tcl.framework/Versions/8.4/Resources, 
which is the equivalent auto_path entry to where it's installed for 
tclsh.

() 1 % package names
http registry dde tclAE tcltest opt msgcat Tk Tcl
() 2 % package require tclAE

Wish goes boom "The application Wish Shell has unexpectedly quit..."

dyld: /Applications/Wish Shell.app/Contents/MacOS/Wish Shell Undefined symbols:
_Tclae_SafeInit

I'll grant, there is no such routine. Does there need to be? TclAE is 
most decidedly /not/ safe.

AppleEvents are delivered to AE handlers asynchronously. No event loop needed.

Actually, what's needed is an AEAddressDesc, which is one of: 
typeApplSignature, typeSessionID, typeTargetID, or 
typeProcessSerialNumber. Can we get any of these for Tcl (tclsh)? 
tclsh has a eunuchs PID; can this be translated to a ToolBox PSN?

Understood. I agree that Tcl should be as "normal" a eunuchs 
implementation as possible.
