I can't test this scenario, but it sounds a lot like using RP in Xnest, 
which works fine.  Here's some debugging steps that might shed some 
light on the problem:

1. On your local machine ("Machine A"), start your vnc application. 
This will connect you to the remove machine ("Machine B").
2. Call xwininfo to get the window id of the vnc application on Machine A.
3. Call xev -id {whatever the window id was} on Machine A.  This will 
show you the events that are reaching this window from Machine A.  If 
you are using RP on Machine A, you may need to split the screen into 
frames to see both the xev output and the vnc application window at the 
same time.
4. Using RP on Machine A, send a C-t to RP on Machine B using "C-t t".
5. Check the output of xev.  If you see something like:
"
KeyPress event, serial 15, synthetic YES, window {window id},
state 0x4, keycode 28 (keysym 0x74, t)...
"
then you know that the RP on Machine A is actually sending the C-t.  At 
that point, it's up to the vnc application to pass it along to RP on 
Machine B.

Also, you might be able to circumvent this problem if you change the 
modifier prefix in Machine B to something different from Machine A. 
This is an old GNU screen trick: C-a on one machine, C-b on another, and 
so on.
