There isn't a way to add unregistered users to a group. Not being able to at least change unregistered user permissions at run time is an oversight on my part. My recommendation is to create channels with specific permissions instead. Any user in a registered channel will be able to use at least everything enabled by that channel. By default, channels allow all users to: work with the whiteboard, talk over voice chat, talk over text chat, and use screencasting.
If you really want to change the permissions of unregistered users, edit imptalkd/src/Authorizor.cpp in the Imptalk source directory and go to line 210 (at time of this writing). Change the permissions you want from "false" to "true". Then recompile and reinstall.
