2.11BSD is the latest, which also happens to support TCP/IP, so all you need
to add to your 11/44 is a DELUA or DEUNA and you get get it on the internet.
Of course another megabyte or two of memory would help too (IIRC you said
earlier that your 11/44 had only 1MB).

I put up a network-ready 2.11BSD configuration that I use on my real 11/44
(and also runs on SIMH) at http://www.AK6DN.com/PDP-11/2.11BSD/
Probably the biggest hurdle would be getting it onto some disk media; it's
a little big for RL02s. The current config uses a 1GB RA72 disk image, but
the total occupied storage is probably less than 100MB.
