FOSS WAN Acceleration Software

[BH <bh05gc () myblackberry com>]

Hello,
I was wondering if anyone had experience or could recommend free open source
WAN Accelerators/Optimizers. There seems to be only one FOSS project called
TrafficSqueezer but development has stopped and the project is still in an
Alpha stage.

I am not interested in the offerings of Cisco (WAAS) or Riverbed (StealHead)
or any other appliance based solution.

Thank-you in advance for any and all replies.
