Possible to have two different sets of tags?

Hi - I am setting up a business self-help site.  It would be really cool if I could have two different tag clouds - "skills offered" and "skills wanted".  Both would be profile fields.  Possible?

Ok, I realize on looking at this further that this creates two sets of problems.  First, once I use the"tags" field for one of the profile fields, it is unavailable for use in other fields - i.e. there isn't another one in the inactive region to drag up there.  Second, if I did some mod that got around that, there would still be the problem of the single tag cloud block - and I am not sure if there is a way around that.

Still, it would be so cool.  Thoughts anyone?

Does anyone know if this is even possible?   Like I said, it would be extremely cool for what I am doing now.
