I'm not sure if this is the right place to propose but is it ok if a sub-site for networking and telecom questions might be created in the near future?
Serious networking and telecom questions are both solidly on-topic for Server Fault.
There've been proposals in the past for a telephony / telecommunications site, but in practice SF seems to cover most of the need.
You can propose new sites by yourself on AREA51. This is the staging site for Stack Exchange.
