Hi,
we've been using the HotDeploy tool for a couple months now, and it has really saved us a heap of time for us.
In particular - when a BA changes some data selection on a UBE we used to have to log into each Citrix Server and get the specs. This used to happen once or twice a day during heavy development periods and could easily take 15+ minutes, and you'd get interrupted and forget which servers still had to be done. Now, we just put the versions in a project - click an icon on our desktop and all servers are up to date in seconds.
We've also used the tool for deploying updates to Citrix Servers as documented in the product spec, and it does this very well - eliminating down time on many occaisions.
This is the handiest piece of software i've used for a while - whoever thought of it deserves a pat on the back
