Yes

Not always. As ex.: allowable MPC5200 JTAG's clock is ... 25 MHz,
clock of 10 Mbit eth is ... + tcp stack overhead. And now we run
memory dump command and measure.

Lauterbach like Lego, constructing from modules: from dumb
LPT<->jtg upto monster-alike in-circuit emulator
(I didn't talk about how _much_ smb. will pay for it,
I talk about possibility).

Yes.

I'm not sure, since I doesn't work with Lb approx. 3 years,
but probably it could.

Don't asking them for a help, since my BDI work as predicted,
so it may be pros also :).
