Mecurial DVCS - your experiences using it

[Foster]

I'm looking for first hand accounts (that means you, not a friend of another robot teams older brothers neighbor) of using Mecurial the distributed version control system. I'm interested in your experiences with Labview, C++ and Java. Specific things I'm looking for:

• What other tools did you use (Netbeans, custom tools, LVDiff, TortiseHg, etc. )
• Things that went well
• Things that didn't go well
• Where / how you hosted a central repository
• How your programming team liked/hated it
• Did you tag versions, how often?
• Tips / best practices you would like to pass on
• Are your desktops Windows or Linux based

Thanks!
(And I know this is CD, but I'm interested in Mecurial. I know that GIT rocks and that real programming teams only use Subversion but your team uses a custom Ruby site from another robot teams older brothers neighbor that had the snow not come you would have used more and no the CVS is not part of the 65 lbs weight limit. Thanks! )
