yes,it is possible,
on the condition you have enough open ports behind your work firewall and your home machine
this is my set-up
at work:
my work proxy is "webproxy" and the port is 2345
this is what I set in my work web browser to get to any web page.. (probably different for you)
they also allow http traffic to go thru ports 80,1080, and 8080
at home:
I have my home firewall allow 80,1080, and 8080 to be open.
I use a program called sageTV (great pvr software) to control my tv capture/tuner via a web plugin that allows
remote control via port 80.
I have vlc running with the http interface listening on port 8080, I also have made and edited .access files to prevent
intruders from accessing the vlc http server
at work:
in a web browser.. I got to my sagetv web page, "home.dns.org/sage"
get sage recording a channel to a mpeg2 file, or verify it is recording to a file..
I get the path and file name from the sage web server. (copy)
I open anther page and point to my vlc web page "home.dns.org:8080"
paste the path/file into the open>input> file name of vlc http
then set the transcoding options of vlc.. (these options work best for my old laptop and home upstream bandwidth)
:sout=#transcode{vcodec=WMV2,vb=768,scale=0.5,acodec=mp3,ab=64}:std{access=http,mux=asf,dst=:1080}
Enqueue the file, vlc http shows it starting to play/streaming via http on port 1080
then on my work/office machine I point my player to
http://home.dns.org:1080
now I can see what my home machine is streaming, and quality is pretty good.
as an added benefit, I can share the stream by using vlc at work to relay the stream to other users inside the office.

and a side note, I record HD streams via a SD capture card and found this to be a good setting for cropping out
the black bars on the bottom and the top
:sout=#transcode{vcodec=WMV2,vb=768,scale=0.5,croptop=60,cropbottom=60,acodec=mp3,ab=64}:std{access=http,mux=asf,dst=:1080}
but if I only want to stream mp3 files from my mp3 collection at home, I use edna
unfortunately I cant use vlc and edna at the same time, not enough open ports.
so before I go to the office I decide if I want music or video..
good luck,
