I have been away for a few weeks so sorry this is being posted so late.

It appears that ebay is going to buy Skype (see http://www.eweek.com/article2/0,1895,1857847,00.asp?kc=ewnws091205dtx1k0000599) which seems like a very interesting move in the world of collaboration.  As yet there is little information on what they are going to be using it for so it will be interesting to see what develops over the next few months.

Will keep you posted !
