Currently, in DIRECT RDP mode, X2GoClient merely acts as a GUI frontend
to a local rdesktop or FreeRDP installation - no X2GoServer required at
all.  In this mode, the X2GoClient GUI allows you to choose between
rdesktop, FreeRDP (old parameter format), and FreeRDP (new parameter
format).

However, X2GoServer also has an RDP proxy mode.  X2GoClient tells
X2GoServer it wants to start an RDP session to a MS-Windows host, then
on the X2GoServer box, rdesktop is spawned and connects to the
MS-Windows host.  On the X2GoClient side, a fullscreen RDP session appears.
So X2GoClient talks "X2Go" to the X2GoServer, and X2GoServer talks "RDP"
to the MS-Windows host.
There is currently no built-in way to use FreeRDP instead of rdesktop in
this mode, rather, the use of rdesktop is hard-coded into the
application (you could, of course, specify a single application session,
and create a wrapper script for FreeRDP that passes all the required
parameters, but, ugh, yuck).
FreeRDP is preferable over rdesktop as it supports newer RDP versions,
so it should speed things up.  That's why I'd love to see the option
being added for RDP proxy mode.

+1.

As usual, a configuration in /etc/x2go/x2goagent.options should override
any client-side configuration, so a rogue user can't bog down a server
that has such a limit intentionally set by its admin.
