deltaplus . I hate to bother them since they've been so busy with 2.0 lately, but I am curious as well :P
We have no ETA as of yet. deltaplus unfortunately retired to focus on other pursuits, so we may need to find a new programmer to "adopt" GiftBot and port it over / continue development. It's definitely on the to-do list.
There is also the complication of XF2.0 not having a proper API for this (XF2.1 has one, but XF2.1 is not yet stable enough for us to switch to).
We'll let you all know as soon as we can confidently provide an ETA.
