have a look at rproxy... it does rsync style delta updates of http traffic. This can buy you more than standard compression, because 90% of http is uncacheable, and most of the volume is uncompressable images. The rsync style delta updates "update" the uncacheable-but-unchanged images with negligable traffic. You can setup an rproxy in Australia using an Asian rproxy parent, giving good delta compression between the two. A decent proxy setup with rproxy for relevant traffic might work out OK. Unfortunately rproxy has not been updated for ages. I keep meaning to do something in Python but never find the time. For other traffic, a compressed tunnel would be pretty simple... just make your tunnel to asia the default route. I'm not sure it would buy you much other than latency though :-( -- ---------------------------------------------------------------------- ABO: finger [EMAIL PROTECTED] for more info, including pgp key ----------------------------------------------------------------------
