I understand you are considering changes to chan_irlp that would prohibit simultaneous connections to both systems at the same time. I'd ask that you at least leave a user selectable flag in the file. For example, on the IRLP Dallas Reflector channel five, I have permission to run other voip systems at the same time. If simultaneous connections are not permitted then I will have to go back to running a separate IRLP node as well.
