sopcast uses very little CPU, so I thought it was a great example for qemu-i386 (which allows running x86 linux binaries on arm linux by emulation) usage. It is possible to run sopcast, but it stops very early, after not managing to connect to the server. I believe it is a qemu problem, as it happens also when I try to run qemu-i386 on x86 systems. I did not really try to debug any further, so it is quite probable that it is some simple issue.

In short - get sopcast to run with qemu-i386 on your linux desktop, after that it will probably work on your tablet as well.
