My take and extension on Chuck's and Allison's question is that you can 
take a USB R232 dongle, and a 56k modem (if your pots line still 
supports it, 33k if not (hopefully), and run a BBS on a Raspberry Pi if 
nothing else for nothing in power and infrastructure cost.

An 11 is novel, but hard to see why running it on simh wouldn't be a 
better deal if you want something on the pdp11 architecture.

Keeping any PDP11 up 24 / 7 so it is a useful BBS isn't an undertaking 
for the faint hearted, nor is it something easy on the pocketbook in the 
way of power.  (not to mention space possibly).

Unless you are a couple of well known museums and others very few do the 
real hardware.
