Trying to use Views to show category with a list of tags from different vocab

I have a 2 vocabs:

vocab 1: category
vocab 2: tags

In category vocab i have terms:

cat 1
cat 2
...

In tags vocab, i have terms:

tag 1
tag 2
tag 3
...

For a piece of content, i have both taxomony (category and tags) fields exposed so i can file the content into a category and use the tags to tag the content.

What i'm now trying to do is create a Views block to show all the tags from a category.

Is this even possible? any pointers will be helpful.

cheers,
