YODCTCS is a graphical interface for monitoring and managing Enhanced CTorrent clients on OpenWrt. (http://sites.google.com/site/yodctcs/home) I made a package dctcs_0.7.2-3_ar71xx.ipk. It contains the latest version of dctcs. Installed on my tp-link wr1043nd. Works fine.
Esound-Enlightened Sound Daemon. I use it to broadcast the audio stream from a laptop via wifi to the speakers connected via usb sound card on wr1043nd. esound-0.2.34-ar7xx-bin.tar.gz contains compiled binaries. ESD daemon works well on wr1043nd.
