[Serusers] Any plans to implement UAC module?

Probably one for Greger- Does anyone know if there are plans to implement the UAC module (as seen in Openser) within the next version of Ser? I am currently running 0.9.6, and when I dial out to the PSTN, the CLI is shown as the Ser username, not the DID number All incoming DID numbers are specified as aliases, so when the PSTN dials in, it gets forward to the correct user. However I need to rewrite the outgoing SIP message, changing the the from: URI so that the alias is displayed, not the ser username. The UAC module is probably the easiest way changing the from: URI, unless anyone knows of a better way??
