Blimey...  An interesting move from EMC - I think I can understand why they're doing it, so that they can offer additional capabilities for securing the storage which they supply.  It'll be quite interesting to see what (if any - purely speculating!) impact this may have on Microsoft.  I've done some work with RSA in the past in the UK, and always found them great to work with.  Not that that will neccesarily change, but I haven't had any engagement with EMC in the UK at all.  So it will be interesting to see how it all pans out.
