Does anyone know if there has been any development on Skype SMS lately?

I currently pay around 25c per SMS in AU, where Skype charges 8.8c... I've been trying to get my friends using IM (msn, gtalk, facebook, skype etc), but most do not have a compatible handset.

Maybe I'm just a tight-***, but I currently use skype over 3g for phone calls and pay around 1/30-1/3 the standard rate (even lower when calling international numbers).
