Some more:

Maybe the easiest Booklet to dissect would be the com.lab126.booklet.test, because it's pretty small (the entire jar is only 33kB, and it only contains a dozen or so classes (including inner classes)).

It can be started using lipc-set-prop com.lab126.appmgrd start app://com.lab126.booklet.test

I haven't figured out how to "operate" it, probably by interacting with it through lipc itself:

[root@kindle root]# (lipc-probe -a -v|grep -A 7 '^com.lab126.booklet.test') 2>/dev/null
com.lab126.booklet.test
	w 	Str	runtest
	w	Str	pause
	w	Str	unload
	w	Str	stoptest
	w	Str	load
	w	Str	go
	w	Str	startresult

And here are the relevant entries in the registry:

Spoiler:

INSERT INTO "handlerIds" VALUES('com.lab126.booklet.test');
INSERT INTO "properties" VALUES('com.lab126.booklet.test','lipcId','com.lab 126.booklet.test');
INSERT INTO "properties" VALUES('com.lab126.booklet.test','jar','/opt/amazon/ebook/booklet/KAFtest.jar');
INSERT INTO "mimetypes" VALUES('runtest','MT:application/x-amazon-testrunner');
INSERT INTO "extenstions" VALUES('runtest','MT:application/x-amazon-testrunner');
INSERT INTO "associations" VALUES('com.lab126.booklet.test','application','MT :application/x-amazon-testrunner','true');
