Yes, exactly -- but with rather stringent limits.
In a nutshell, during the replay session, you must give
EXACTLY the same sequence of gdb commands as were given
during the record session. gdbreplay will prompt you for
the next command, but if you do *anything* different,
it will throw up its hands and quit.

Not yet -- but that's part of what I have in mind! ;-)

Yes -- but you can run gdbserver on a native system, i.e.
"target system" has a rather broad meaning in this context.

Not yet... ;-)
