I have a group who I often play different FFG40k games with, can't say we're the best at it yet as we've only been doing it a few months but we've done
RT,
OW and
DH games in the past. We use skype for the actual games but they can be organised on
my roleplaying site which may interest you. It does have a relatively new section specifically for pen & paper roleplaying games. There are about 9 or 10 from amongst the site's community that tend to participate in our
FFG roleplays so if you had the skill to organise one (or one started up that appealed to you) then I imagine you could get involved in a game fairly easily.
