In the post
viewtopic.php?f=48&t=11186&p=38132#p38132 you mentioned your problem with VirtueMart and the developers version. Of course you can get the latest developer version here
https://github.com/JoomFish/jf-future and try it yourself, from what I've tested jf-future has improved quite a lot since that post.

"Alpha" means that you cannot expect it to work flawlessly, but it's ready to take a peek and try things. See for example Klas' post
viewtopic.php?f=48&t=11356&p=38745&hilit=alpha#p38745 (Klas is working hard on jf-future as you can see from the commits he does:
https://github.com/JoomFish/jf-future/commits/master).
Note: I haven't tried jf-future (nor JoomFish 2.2.3 for that matter) with VirtueMart, I have tried one other third party component with JoomFish and that had a problem which I want to look into before posting it as an issue.
