There is a trick for everything :)  For \ref{} / \pageref{} there's xr
package, but doesn't work for \cite{}.  The trick is to grep the
\newlabel / \bibcite stuff from your main document aux file(s) and
input that in your IPE graphic, e.g., put in the graphic preamble
(requires -shell-escape option):

\immediate\write18{grep -E 'newlabel|bibcite' mainfile.aux >> \jobname.aux}
