mod_accel can work with mod_rewrite as mod_proxy does ([P] flag)
but mod_proxy would loose this functionality if mod_accel installed.
In all other cases mod_proxy can work with mod_accel in one Apache.

But mod_accel can simply proxies request without caching.
You can set 'AccelNoCache on' on per-server, per-Location and per-Files
basis. You can send 'X-Accel-Expires: 0' header from backend.
You can use usual 'Cache-Control: no-cache" or Expires headers.

With mod_accel your mod_rewite using can be eliminated with
AccelNoPass directive:

AccelPass      /    http://backend/
AccelNoPass    /images  /download  ~*\.jpg$

I have plans to make mod_accel Apache 2.0 compatible but not right now.
I wait Apache 2.0 stabilzation.
As to mod_proxy, I've wrote replacement for mod_proxy because
it's to difficult to hack it. It was much simpler to write module from
