I'm a fan of embedded system hacking, but primarily a UI designer and web application engineer. I've never found a web interface on an embedded system that was pleasant to use or well architected and i'm itching to develop one for OpenWrt (perhaps start with the X-WRT trunk).
I don't want to develop for a project that has no longterm future, so i'm asking others what you speculate the lifespan of OpenWrt is. I've been using it on a Linksys WRT54G for two years and haven't been following what other devices it works on and what the growth is. Does it even work on any draft-n routers?
