[c-nsp] PFC-based EoMPLS and MPLS-TE

I was wondering if anybody has mixed EoMPLS and MPLS-TE, running on
PFC-based MPLS (Sup720, ME6524 and related platforms) in a scenario
like this:

PE1 -------- MPLS Cloud with TE affinity bits ---- PE2

PE1 and PE2 have an EoMPLS xconnect with each other, targeted at each
router loopback. Affinity bits are configured on the links on the
cloud based on whether they support Jumbo-frames or not. First part, a
tunnel is created with affinity requirements such as it will always
use "interesting" links; then, a static "ip route <other routers
loopback> tunnelxxx" makes all traffic between PE1 and PE2 go thru
that tunnel.

Can this scenario work ? WIll LDP run thru the tunnel, as EoMPLS opens
an LDP session between PE1 and PE2 ? Running thru the tunnel or not,
will LDP correctly allocate labels so the EoMPLS connection goes thru
? Will this adversely impact the other traffic between those PEs,
besides the fact that all PE-to-PE traffic will now follow the tunnel
?
