Client Access Express on a CISC system

I'm getting confused.

Client Access Express ("Express") has a smaller cleaner footprint than
the classic Client Access for Win95/98/NT ("Classic").  But I also
thought that was because some things were "missing" in Express (like
APPC and IFS access).

I thought that Express required Netserver to get at the IFS on the
AS/400.  If this is so, then Express is not usable (for me) on our CISC
(read V3R2) system.

However, I have been told both of the following recently:

1) That is correct.  There are things you _cannot_ do on a CISC if you
use Express that you _could_ do if you used Classic.

2) That is wrong.  As long as you stick with TCP/IP connectivity, you
can do _anything_ in Express that you could do in Classic.

Which is right?
