build frame relay "hub" similar to ISDN "hub"
tnt and I did some initial testing, and it's possible to use dahdi-trunkdev with dahdi-net similar to what is described in Linux_generic_HDLC_layer_+_DAHDI. This means we can build some kind of hub for HDCL or FR communication to which peopel can remotely attach FR/HLDC routers via icE1usb.
I'm currently thinking to go straight for FR (more interesting, can play with SVC/PVC).
This could be an entirely separate machine/VM with dahdi-trunkdev, osmo-e1d etc.
