Do IBM,...
... still use Notes as their internal mail platform?
I used to use 'BigFix' when I was Blue, it was a buy in, originally called BigFix, then renamed to Tivoli Endpoint Manager, then IBM Endpoint Managed, then IBM BigFix, and i guess now, HCL BigFix.
Odd for IBM to sell tools it uses internally, sure they'll rake in some dough, but end up paying via licenses, Wikipedia reckons Big Blue still has ~366,000 employees, That's a lot of revenue for HCL.
