It looks like nyaruka's Android SMS relayer app isn't yet publicly available or open source, but in the meantime people can also check out EnvayaSMS (http://sms.envaya.org/). Notably, EnvayaSMS also relays incoming MMS and allows you to exceed Android's limit of 100 outgoing SMS messages per hour.

[Sorry for the self plug, but this is too cool to pass up] 435 days ago I first publicly "launched" KalSMS in an HN thread - http://news.ycombinator.com/item?id=1759871 - the codebase was later picked up by Envaya, greatly improved and morphed into EnvayaSMS. Cool to see people recommending it :)
