Using the indirection capabilities of SelNet, we can construct on-demand chains of proxies for adapting content for mobile devices. Daigan takes a specification of a device's capabilities and from that identifies which proxies are needed to meet these requirements. Based on this specification Daigan sets up a chain of proxies and transparently redirects an application's traffic to the proxy chain. We demonstrate Daigan's abilities through a scenario which performs the instantiation of a proxy chain consisting of a proxy cache, an image transcoder/compressor and a TCP header compression proxy. We describe this scenario in detail and report on implementation progress.} }
